- How to make Sodium hypochlorite bleach from calcium hypochlorite, caustic soda (NaOH) and soda ash ( Na2CO3). The Chemistry of the process involves the :
1. Splitting of calcium hypochlorite into free Chlorine and calcium hydroxide
2. The reaction of the free chlorine from 1 above with sodium hydroxide to yields sodium hypochlorite bleach.
In this reaction Chlorine is reduced to Cl (-1) in NaCl and Cl (+1) in NaOCl. This a type of reaction is called Disproportionation reaction.
I love your teaching.
Thanks for this video
Thanks a lot ❤
Can you tell me about the percentage of your calcium hypochlorite sir ?
Thank you very much for this. God bless you
Uwcm Sir. Thank you for watching my videos
Finally I found the information i was looking for. Thanks a lot.
If I want to make just 20L of bleach instead of 40L, can I just reduce the quantity of ingredients to half? Or is there something else to consider ?
Reduce the quantity of the ingredients to one-half, for 20L of the products. Or to one-quarter for 20L of the product if you consider cost of materials but the potency of the final product will be compromised.
@chemistrymadeeasy3334 Thank you for the quick response.. I will keep that in mind.
@Utibe-Tutor, what's the concentration here in percentage SH.
What is the difference between sodium hypochlorite and Calcium hypochlorite
IN TERMS OF USAGE:
1. Calcium hypochlorite is an intermediate material used for making sodium hypochlorite.
2. Calcium hypochlorite is a source of chlorine for making sodium hypochlorite.
SIMILARITIES:
Both of them are bleaching agents but sodium hypochlorite is a stronger bleaching agent than calcium hypochlorite because it ionizes completely in aqueous solution to librate the hypocrite ion which is the active chemical species in this regard.
Wow I like it
Thanks for watching my RUclips videos
Thanks so much for this teaching. You are good at what you do. Thanks dear.
Pls is it true one can add HCI to this solution, what's the effect? Urgent pls
HCl will liberate chlorine from the bleach solution. Pls do not add because this reaction is not safe
Good evening sir . I got project to make min 12% sodium hypochlorite .what formulation u suggestion? And i try the receipe like u do in video .. when i finish all ingredient the solution look have a good appearance but after 20 hour the solution separated ? Can u explain ? And what your advise ?
@@yopieirawan9408 let's chat on WhatsApp pls. +2347058424098
very clear explanation sir! just a quick question, the sodium hypochlorite that you made in this video is how many percent? is it 12 percent sodium hypochlorite?
Thank you for your comment. This hypocrite solution is about 5%w/v
You are a great teacher. Thanks a lot
Thank you! 😃
I love your teaching the best teacher. Merci beaucoup, Bon enseignants je vous remercie. À bientôt d'accord ?
Thanks you
Mohtaram ,aap ka bohat shukria ,
Sorry I don't understand your comment
It means ,thanks
How does it smell?how long it's smell stay?
Thank u sir can I use normal cooking salt
I love your teaching sir
Thank you for your comment
What is the percentage of this sodium hypochlorite?
This is about 5% w/v
Good explanation.God bless
Thank you
Thanks you Sir for this Video
Love from Pakistan🇵🇰
Thanks too, hope you have subscribed?
Thank you for your information sir if i want the product have good smeell how can i add fragrance on it ....
Hypo has a strong antiseptic smell which is difficult to mask with any other smell. This strong smell is what defines a good quality hypo. However, if you still insist on adding a good smell to it you can try adding a spoonful of strawberry.
Please sir, I need measurements for 5litres. Moreover, can smone add industrial salt to this solution?

What is actual use of this bleach in water at the time of floor cleaning , toilet and other surfaces ?
@@rajendrawaman1799 Question not clear pls. Rephrase your question
Means what quantity of bleach diluted in water ?
It useful to swimming pool water treatment?
Thanks for this video trying to formulate a drum of bleach. Would would be the formula?
How many litres is your drum? Find out what the capacity of your drum is then convert the ingredients to the capacity of the drum.
Eg: (for a drum of 80L capacity)
Caustic soda:
1kg = 40L
-------kg = 80L
Answer= (80 x 1 ÷ 40) = 2kg

How to make naclo2
Thanks for the very valuable information. Is that considered to be 12.5% Sodium Hypochlorite?
Ok.. I saw that other people asked the same question. I'm interested in making higher concentrations.
No this is about 5% w/v sodium hypochlorite
Hello. Is this the type of bleach that can also be used as disinfectant?
Concentration is strong enough to kill germs. It is recommended for disinfecting toilet bowls, cleaning of floors and surfaces but not for surgical tools/ clinical uses
Please ,inform about shelf life of product and how we can do to improve shelf life of product
The only condition that reduces the shelf life of sodium hypochlorite bleach is light. As long as the product is stored in an apaque container the potency will last up to 3years
Very good tutorial your explanations were comprehensive
Good teaching thanks 🙏

Please sir, is it necessary to add industrial salt ?if yes which quantity sir, and what is it function.
Also sir, what is the cause of some bleach when use to wash white dresses ,it turn it to cream white ?
Industrial salt is common salt (sodium chloride) that has not been refined. It doesn't add to the quality of bleach. What makes a potent bleach is the amount of sodium hypochlorite in it.
For your second question: Sodium hypochlorite bleach does not actually remove stains or off-colours from white clothes but covers them with white shade. So as you wear the clothes the white shade wears off and the "off colours" are re-exposed.
@@Utibe-Tutor thanks, so it is not necessary to add industrial salt. right??
Please why is that some people add it to their bleach ?
Then why do I keep seeing people use electricity to make it ?
Can I used this in the pulp for paper making sir ?
This solution is not strong enough to bleach pulp for paper making.
Can i bleach denim jeans with this
How can you make bleach for coloured clothes
Pls sir,can I leave it for 2 to 3 days before filtering. Some people said ,d longer it stays, d stronger it becomes
Yes the longer it stays the stronger it becomes provided you keep it in the dark because sunlight decomposes it. I hope you have subscribed to my channel
Yes sir.i subscribed. Can I add hydrosulphite to my bleach
Please can I also add industrial salt to this solution and what quantity.
The product already contains salt as a by-product from the reaction. You don't need to add industrial salt again. Industrial salt is merely a preservative and a drying agent which is not needed in bleach
Can a hydrometer be ysed the chrck the exact chlorine concentration?
No hydrometer does not work here. It is iodometry that works
Please sir.
Thanks for the video
I am confused with the comments
What is the concentration using this formulation.
And what can i do to get 6% concentration for medical purposes
The recipe of 2kg of Calcium hypochlorite + 1kg of caustic soda + 2 Kg of soda ash in 40L of water gives a bleach of 2.3% w/v sodium hypochlorite concentration. For 6% concentration you need to vary the quantities of the materials. Give me some time to work on this for you. Remind me after about one week from today.
@@Utibe-Tutor ok thank you
@@Utibe-Tutor Please I also need to know thank you!
@@Utibe-Tutor please ma. I will like to know too.
Thank you for the video.
Please ma can we add industrial salt too.
What is the concentration of Sodium hypochlorite made by this way?
The concentration of the sodium hypochlorite bleach made in the video is 0.35mol/dm3 or about 5% w/v
Please can it be used for disinfecting medical instruments?
Yes, it can be used but ensure that you rinse the instrument with distilled water several times after treat
Pls is Calcium Hypochlorite same thing as Chlorine?
Yes, commonly called chlorine. It is white crystalline solid with a chlorine or hypo smell
@@Utibe-Tutor ok, tanx for your response sir
Sir what we can add more water in final sodium hypochlorite..????
It is better to add more water to the bleach in the course of making it than to add water to the final product.
What can add more water in final product...if we want to increase thier quantity?
No
Thanks sir
Which soda ash light or dens ?
@@rajendrawaman1799 Soda ash dense
What is the difference between light & dense soda ash
@@rajendrawaman1799 dense is more caustic/concentrated than light
very nice . but i want to make 5.25% sodium hypochlorite can you help me please because i want to make high quality bleach like clorox
This requires serious calculation. Why do you want to make strictly 5.25%? . Household bleach ranges from 3% to 6%.
@@Utibe-Tutor i want to make high quality bleech same like clorox . if 5.25 is not possible can you help me to make 4 to 5 % sodium hypochlorite
Percentage of active chlorine? Not the overall concentration.
Because i see on some products on the market i see( 8⁰ Cl 2.4% c.a)
The bleach made this way does not have free chlorine. The chlorine is present as sodium hypochlorite
What is the percentage of sodium hypochlorite in this bleach solution?
Sir thanks for sharing this formula
But can you tell me which water we used normal water ,mineral water or Hand pump or salt water because we used salt water with calcium hypochlorite for washing clothes it work fast plz tell me.
Normal water from a good source pls. Not salt or deionized water
What's suitable ratio for cleaning black soiled tiles.
This is recipe gives a bleach solution which Is suitable for your request.What you will only add is powdered detergent.
Sir,
how much Quantity of water can be added to this cleach to wash our clothes?
For white clothes only: Take one cup of bleach and add to 3cups of water. Then add your detergent to this mixture and brisk it then soak your clothes inside for some hours before washing, scrubbing and rinsing
Can it use for making detergent powder
No. Only use it in combination with detergent to wash your white fabrics.
Can we use for fabric dyeing sir
Sodium hypochlorite bleach cannot be used for fabric dyeing
Can we use Chlorine instead of Calcium hypochlorite?
No, chlorine in water is not stable as it changes to HCl and HOCl so it won't make a stable bleach
Please will be happy to see a video on how to calculate the concentrations of this mixture
Video on how to calculate bleach concentration will be out soon
No, chlorine in water is not stable as it changes to HCl and HOCl so it won't make a stable bleach
Hi! Did you subscribe to this channel? Video on how to check the concentration of bleach had been uploaded.
@@Utibe-Tutor yes
Pls if I want to do 25litres what is the measurements???
Do the simple proportion Calculation
Eg 1kg of caustic soda is to 40L
Then xkg of caustic soda is to 25L. Find the value of x . That is, x = 1x25/40 = ......
Do same to other ingredients
Sir can this bleach be used to sterilize medical equipments if yes what’s the dilution ratio
The bleach made this way is suitable for household disinfection. However for sterilizing medical equipment 6% concentration is effective. Give me some time to carry out titration on the bleach so as to establish its actual concentration and tell you how to dilute or concentrate it for medical purpose cos some pathogens can be really stubborn.
Can I double the Ingredients in the same 40L of water to make 10% concentration?
No if you double the ingredients you will only make 4.6% ( ~ 5% w/v) hypochlorite concentration.
@@Utibe-Tutor thank you for your reply.
I use alot of SH to wash roofs. I would like to make large quantities. I have a 1000Litre poly plastic vat. Would I be able to use the same ratio of ingredients in say 800 Litres of water? And would the reaction in a large quantity like that take longer than 24hours?
Is there any way to make a stronger concentration with this method?
Sir can u make a video for sodium hypochloride making for fabric bleach
The sodium hypochlorite (bleach) production demonstrated in the video is fabric bleach
@@Utibe-Tutor ok sir
if i make 52.63 l of water end 2 kg hypo cla end 2 soda ash end 1 kg causitc soda i can have concentration if 3.8% or 12° or no
Sorry this will further dilute the bleach solution.
@@Utibe-Tutor but Can delute thé final solution to add 1'5 l
What would be the chemical ratios to make 12% sodium hypochlorite?
Calcium hypochlorite 4800g, caustic soda 2400g, soda ash 4800g, water 40L. But this preparation is not advisable
hey thanks for the information!
but why is it not advisable?
@@ahmadshatila6329 The concentration of the bleach will be too high for domestic use.
oh , yes sure.. you are right 👍🏼 . do you have a page on Facebook? your videos are very helpful
@@ahmadshatila6329 No
can I use PET bottle as its container?
No use HDPE. The product will attack PET because of residual lye in it
@@Utibe-Tutor Got it. Thank you for replying!
Please make another video explaining how sunlight affects bleach thank you
Is it how sunlight affect a bleach solution when exposed to it or the fabrics washed with the bleach solution when exposed to sunlight? Sorry clarify please.

how much chlorine and how much soda ash ?
Calcium hypochlorite (commonly called chlorine) in the recipe is 2kg and soda ash is 2kg too
Percentage of Chlorine in this formulation
Sorry there is no free chlorine in the formulation. There's only a compound of chlorine - sodium hypochlorite which is the active ingredient in the bleach
@@Utibe-Tutor you didnt add chlorine to your list of items. Does it mean if we are using sodium hypochlorite , we shouldnt use chlorine, but caustic soda and soda ash ?

What is the ph value sir?
The pH is 10.6, concentration is about 0.35mol/dm3
Please ma if it is for business, which measurements can I use.?
Please your question is not clear
@@Utibe-Tutor please I am asking if I was to sell ,will this quantity of ingredients to 40 liters of water give me a profit??
So I wanted a recipe for business.
The quantity of the chemicals u gave some people used it with 90 liters of water, I don't know if it is correct.
This quantity is for 5% sodium hypochlorite bleach which is recommended for house hold use. This gives you a bleach with a pale yellow colour which is best. However if you double the water the bleach becomes colourless and less effective and will not last long on shelf. You will also receive negative feed back/complaints from your Customers. But I would advise you follow this recipe or if you must increase water don't let it exceed 60Litre.
@@Utibe-Tutor Thank you soo much, may the joy for given me a kind reply, bear good fruits in your life in Jesus name.May you live long, may you live long.

Yeah, that's what I wanna know. What's the percentage of SH here? This would be worth doing if you're getting a high concentration that you can highly dilute. If the concentration here is no more than 10%, then you're better off buying it in a store. I've done the math on everything. I do soft washing for a living, so I would love to start making it, I could save a fortune, but not if it's not pure.
