Hello, What are the references used for this test? Are they from APHA, AWWA, and WEF?

Which equation was used to get the grams

What is the aim of this experiment

Have a nice day. Thank you for video and I have a question. One of my students do this experiment with EBT indicator last semester with her old teacher, and she didnt observe the color change pink to blue, but grey to blue. What can be the reason behind it, and Should we repeat the experiment because it is for SL internal. Thank you.

It was really helpful. Thank you.❤

It is use to find titration in cosmetics?

Are NaClO and OCl- the same?

great video, concept clear explanation.

Can you comment on the results of total hardness

شكرا❤

Thanks for the help but I somehow ended up with 9000ppm... definitely a me problem lol

absolute legend

Hi, must our indicator be solid? Or can it be in liquid form. Also if it is in liquid form, that means we must add more of it?

God bless you sir

I still don't get it. Why in %w/v, it's divided by 10?

thank u so much i owe 10% of my grade to u

Very helpful, thank you.

what is the concentration of EDTA?

Repeating this experiment with Deionized water what should we expect?

Thank you so much, your video was really helpful, greetings from Venezuela

watch out for city patrol highway drivers in yellow ... pretendenting to be cab drivers of colleges around the city from Heathrow to Alaska ............. .... metric titration to determine the hardness of water .......... erichroma t ............... indicator ..... hundred mils ......... the physics department have eloped with the spectrophotometer and the lab attendant cannot answer the income tax details ......... which is with vinayaka mission university ...... aarupadai veedu institute of technology ...............assistant professor ..grade two ............ how account exists without the employee ..........

i love you

what is the name of the ph10. buffer product?

If I am titrating to find the effect of (temporary) water hardness due to temperature, is it alright if I use this method for total water hardness and then determine the effect of temperature on the change in water hardness (which would indicate the change in temporary water hardness)? How long would I have to let each water sample be at each temperature, before removing from the heat? Lastly, once it cools down and I carry out the titration, should I rinse the water pipette after every trial OR after every interval of water OR not at all? Would greatly appreciate your help and thanks a lot for the video demonstration!

Amazing explanation

Thanks a lot bro💚🤎may my school give you all my tuition fees

Thanks, super helpful!!!😊

Where did the 9.8 come from?

To measure 100 ml of a water sample you used 25 ml pipette 4 times, but would it be better to use a 100 ml measuring cylinder? I thought this would minimize the bias, but at the end I'm not sure

Thank you very much

thankuuuuuuuuu sir

What non sense writting on 0paque surface

This was very helpful!

How to get know whether the value obtained in burette is correct??

Greetings.Please help me out with this Given 25.4g of I2 in 6g KI per dm3 24.82g Na2S2O3 per dm3 Also given Na2S2O3.5H2O Help me work out the end point of the Redox titration using starch solution Thanks Chidozie Ofoegbu

Could you please explain how you got 0.07 mol/L? Thank you.

Thanks a lot for helping me write my report..😙😙

Excellent! Thanks very much

Thank you! I am a college student and I found your video very helpful.

GREAT EXPLANATION

What would you do suppose you have a water sample that you want to test for hardness and you find it is too hard that Even after adding all the EDTA the end point is not reached? Help please

Niall Horan being a chemist

How did you prepare the EDTA solution?

Reading ky h sir

Yuckkkkk

So complicated

When the titration only takes 3 ml

hi! if we need to calculate the mg and calcium in milk, do we also assume caco3 during the calculation?

Very clear explanation. Thank you

Thank you sir bless ya heart
