Idk how you did it but FuseSchool, after a year of doing titrations and just having to copy other people’s answers and calculations, I have finally understood what a titration does and how to calculate such in just 5 minutes. That’s a feat of a great teacher.
I honestly can't articulate how much I appreciate this, I know the vid was posted five years ago but I was so frustrated with this I was about to quit chemistry and now I have a good grasp of this! thank you so much :))))
For Step 3: Calculate concentration of unknown solution, where did you get 0.5 x 0.02 from for the known solution and where did you get 0.01 divided bt 0.04 from?
my teacher uses a long method called the box where u do a lot of fractions multiplied by each other and i don't even know how to do it this is way simpler thanks
Thank you so much I watched so many videos and didn’t understand anything... you broke down everything simple in 5 mins .. thanks for giving me the confidence and understanding to smash these questions now !!
thank you i have a titration practical after few hours and after struggling to understand moles for whole night i just found your video and it really helped me...i think im gonna pass.
Hi there is an error in the first titration calculation. 0.01/ 0.025 is not 0.04. Also one of the annotations is incorrect in the sulphuric acid titration (same annotation as the first titration). Nice videos though.
Teacher teached this for like 2 damn weeks and I couldn't get a damn. This video was easy to understand and I learnt the calculation almost right after the video. 🙄🙄🙄 Wish I found this dude earlier
Man.. They have explained this so well compared to my teacher who did but however, used too many incomprehensive terminologies that made it seem more like a set of floating Chinese characters. They also have awesome diction and this dude is an awesome narrator like really.
For the purposes of this calculation we are assuming that one mole of the known solution reacts with one mole of the unknown, so once you have calculated the number of moles of the known solution that have reacted, this will be the number of moles of unknown. If the two solutions react differently, say 1:2 or 2:3 (it will always be a simple ratio) then you have to include this fact too.
To calculate mass of Na₂CO, in solution, if for titration analysis used 22.00 ml of solution H₂C₂O4 which equivalent concentration is 0.1000 mol/L. Solve it
Step 3 tells us to find the molarity of the unknown solution by dividing the moles of the known solution, by the volume of the unknown solution. How does this make sense?
maybe they assumed that they already know what exactly the substance is in the unknown solution (like in the 2nd example). Therefore, they can write the equation and know the moles ratio of the reactants. So maybe the reactants moles ratio is 1:1. But in the second example, the ratio of sodium hydroxide to sulfuric acid is 2:1 and they still plug the moles of NaOH to H2S04. which is incorrect i think.
@@fuseschool thanks for replying.... I thought i missed something out too....I spent the last half hour trying to understand why everyone in the comments were saying it was so easy. It is easy, but concept is easy to understand here, but the final answer is 0.4.
I completely understand the maths behind the answer to the last calculation, but the logic doesn't make sense: if substances neutralise they must have the exact same amount of stuff in total, and since the two substances had the exact same volume they must have had the exact same amount of stuff per amount of space in order to total the same number of moles, so how can a volume with a concentration of 0.3 mol/dm^3 neutralise with an identical volume that has a concentration of 0.6 mol/dm^3?
You are nearly right, but remember that a di-basic acid, such as sulphuric acid, has two replaceable hydrogen atoms per molecule, but an alkali such as sodium hydroxide has only one -OH group per molecule. So you need two moles of NaOH to neutralise one mole of H2SO4. Check out the video at 4:00 again.
Were did they get the 0.01 from? They seem to have carried it over from the mole value for sodium hydroxide which if you are going to do you carry it over and divide by 2 to get the mole of sulphuric acid and go from there
Hi Sir would you be able to help me with this or someone else In a titration a 125cm3 sample of nitric acid reacted exactly with 10cm3 of 0.40mol/dm3 potassium hydroxide solution. Calculate the number of moles of potassium hydroxide used? Many thanks
Sort of... But you can only use M1V1 = M2V2 when the mole ratio is one to one... If the mole ratio isn't one to one, it's better to go through the long way to ensure you don't make any mistakes.
FuseSchool i am extremely sorry..it was today i went through my chapter and the video and you are right. there were 2 moles of HCl for every 1 mole of Ba(OH)2....so it is correct ... 4:41 sorryy
NOTE: at 2:00 concentration calculation should say 0.01 / 0.025 = 0.4 mol/dm^3
I checked the answer 10 times
@@HZrelaxview same
Yes, I got 0.4 as well.
In approximately 2 minutes, I finally understood what I couldn't in a month of class.
Glad we could help!
Really true
In a frigging nutshell😂
you sir are a living legend and life saviour to us chemistry failures, thanks a bunch, looks like im not failing anymore! :D
Happy to help!

I want fuse schools to be given an award for services towards humanity
Thank you!!
This tbh I agree

So great to hear that! Glad it helped!
Thank you sooo much for these 2 videos!!! They really helped me! You guys are amazing!
Glad they helped 🙂
one of the easiest videos I have ever seen!
This 5 minute video taught me more than the month of titrations I did thank you now I have some hope for my test
No problem! And good luck! 🙌
Ok, this just saved my grade. THANK YOU
For Step 3: Calculate concentration of unknown solution, where did you get 0.5 x 0.02 from for the known solution and where did you get 0.01 divided bt 0.04 from?
Amazing, an actual video that straight to the point, shows formulas and explains everything. You just saved my grade on my midterm
Glad to hear that!
For the question at 4:30, if the molarity of HCl was wanted while the molarity of Ba(OH)2 had been given, would we multiply the result by 2??
my teacher uses a long method called the box where u do a lot of fractions multiplied by each other and i don't even know how to do it this is way simpler thanks
After 2 years, I can proudly say that I can work out titration and its calculations, thank you!
Thank you so much I watched so many videos and didn’t understand anything... you broke down everything simple in 5 mins .. thanks for giving me the confidence and understanding to smash these questions now !!

Wonderful!!! Lovely!!! Understood what I couldn't in 3 years of classes. Thanks!
Thanks,, the visualised calculations are totally helpful
thank you i have a titration practical after few hours and after struggling to understand moles for whole night i just found your video and it really helped me...i think im gonna pass.

Thank you I finally understand. My chemistry teacher is terrible at explaining things
Idk why was everyone teaching this topic was making more confused and fuse school just explained it with just 2 examples 👏👏
Thank you so much my school was not helping very much but now I actually understand I was gonna cry in the lab
So helpful and easy to understand
This was really helpful thanks, you make it so easy!
Thanks for explaining

Gareth Marks love your corrections its good to be alert
I disagree .01/.025=.04
the answer is 0.4
@@bernardmukenye5863 lol "concentration" how punny
Thanks, I thought I was going mad
Why did you put 0.01 as the moles for the unknown solution? Are the moles of the known and unkown solution same?
We have assumed that in the equation for the reaction, 1 mole of known reacts with 1 mole of unknown. But it could have been 2 to 1 etc.
You just saved me from not passing in just 5 mins. Why can't all lectures make it this easy?!
Thank you!!!
Thanks so much for the positive feedback!
Does this apply to ALL types of titrations? Like double titration and redox and everything else?
I COME BACK TO THIS VIDEO ALL THE TIME FOR TITRATION EXERCISES IT'S AMAZING!!!!!
Awesome 😃

Fantastic class
Can u please make a video on titration for finding alkalinity of water sampla
Thanks this helped a lot!
Thank you
Welcome!
teaching nicely in 3 mins mad lad
Cheers 🙌
Absolutely amazing videos. Thank you so much :-)
Thank you too! Glad you like them!
u explained in 5 mins what i couldn't understand in a whole year
Happy to help ❤️
Thanks alot ❤
Always welcome 😊
hit like if u have your chemistry practical tomorrow and its already 12.30 AM
no but it is 10pm and I have a test tomorrow
I feel like i'm the only one who is even more confused now than before I watched the video
thank you lord. I understand more than what our teacher taught us
This acctually helped
Awesome!
Thanks. This was of great help.
and that is how I passed my 30 marks Titration test, boys. Thank you so much FuseSchool!!
Awesome! Glad we could help 🙌
Pls check ba(0h)2 is in one mile only so no need of dividing with 2 pls confirm this
you are amazing. thank you
Thank you too!
What about when the concentration is given in Normality?
The most helpful video thank you so much
Glad you think so!
Thank you so much very helpful!
You're welcome! Glad it helped!
How did you get the mole for the unknown at 1:58
For the purposes of this calculation we are assuming that one mole of the known solution reacts with one mole of the unknown, so once you have calculated the number of moles of the known solution that have reacted, this will be the number of moles of unknown. If the two solutions react differently, say 1:2 or 2:3 (it will always be a simple ratio) then you have to include this fact too.

To calculate mass of Na₂CO, in solution, if for titration analysis used 22.00 ml of solution H₂C₂O4 which equivalent concentration is 0.1000 mol/L. Solve it
at 2:19 is it know concentration X (Volume of known/ Volume of unknown) ?
You may have forgotten to mention that the first example assumes that you have a 1:1 ratio btw :)
Step 3 tells us to find the molarity of the unknown solution by dividing the moles of the known solution, by the volume of the unknown solution. How does this make sense?
lol at the moment i am wondering that too ?

hi guyz that was perfect to me and now I'm charged up with these calculations
2:00
0.01 / 0.025 = 0.04
Nani?
There's an error in that calculation. Well noticed!
@@fuseschool Have you fix the calculation now?
@@karinaroosvita once a video’s out. They won’t be able to fix that calculation without losing lots of views.
@@aquiIa_chrysaetos so ur just gonna leave wrong information published
@@tasangerbakes yeah that’s kinda a really shitty thing to do. Makes me wonder what else they swept under the rug
this guys voice is big brain
my saviour
at 2:00 is it just me or is the answer wrong for the concentration of the unknown substance. 0.01/0.025 is equal to 0.4 not 0.04
It should be 0.4, you are right! Thanks for noticing!
@@fuseschool thanks for replying.... I thought i missed something out too....I spent the last half hour trying to understand why everyone in the comments were saying it was so easy. It is easy, but concept is easy to understand here, but the final answer is 0.4.
how do we know both of them have the same moles?
like if we find the moles of know how do we know the unkown also has same mole?
ye
NICE VIDEO
this really helped me, my teacher was terrible at explaining to me
Wow perfect 👍👍👍❤
Thank you 😃💜
Isnt it 0.4 mol/dm3
Yes it is
You are right. There's an error in that calculation. Well noticed!
I’m still slightly confused on why the known solution has the same amount of moles than the unknown. That makes zero sense
That is what confused me also
Sometimes the two solutions react one to one, and thus has the same amount of moles.
This helped a lot, thanks : )
Glad it helped!
You can directly give a formula instead of this much explanation (N-a×V-a)=(N-b×V-b) dilution law
Thank you so god damn much
Most welcome!

What if the mole ratio is not 1:1??
I dont understand in the end how/why is it 0.6÷2
how i can find average moles
rip to my homies using liters/mol
Too good👍🏻♥️
Thanks a lot 😊
Is it just me or is their an error in the concentration calculation of the unknown substance. 0.01/0.025=0.4 not 0.04?
nobody asked
Were did they get the 0.01 from? They seem to have carried it over from the mole value for sodium hydroxide which if you are going to do you carry it over and divide by 2 to get the mole of sulphuric acid and go from there
Yup, you are right, there's an error. Sorry about that!
Wesley Allen exactly what I thought, I’m extremly confused
Hi Sir would you be able to help me with this or someone else
In a titration a 125cm3 sample of nitric acid reacted exactly with 10cm3 of 0.40mol/dm3 potassium hydroxide solution. Calculate the number of moles of potassium hydroxide used?
Many thanks
No
0.032 mol/dm3 i think
@@olliecowdall4545 nice try man but it's actually 0.32mol/dm³
@@olliecowdall4545 yeah thats right
@@olliecowdall4545 HI
Best
2:02 there is an error it is 0.4
Yes, you are right. Thanks for noticing!
Like your videos
0.01/0.025 is equal to 0.4
I think so too
You are right. There's an error in that calculation. Thanks for noticing!
Your wrong in that practice question. you're meant to divide 0.015 by 2 instead of mulitplying
First one is wrong
But how do i find the molarity
molarity is the molar concentration given by M/L
so you might have to change units
0.01/0.025=0.4
at 2:00, there is something wrong
It should be 0.4, you are right! Thanks for noticing!
2:00 its 0.4 not 0.04 ...
You're right! There's a mistake. Thanks for noticing!
Wtf thanks man
audio is too low :(
voice very low
this is just a fancy way of saying M1V1=M2V2
Sort of... But you can only use M1V1 = M2V2 when the mole ratio is one to one...
If the mole ratio isn't one to one, it's better to go through the long way to ensure you don't make any mistakes.
Who's here for gcse 2018?
I like ur video design but the information is not the best.
what the hell happened to the stoichiometry?
THERE WAS ONLY 1 MOLE OF BARIUM HYDROXIDE....WE DONT NEED TO DIVIDE...THE EQ IS BALANCED RIGHT ???? PLSSSSS REPPLLLYYYYYYYYYYY.....
What part of the video do you mean? Give me a rough time and I'll check for you.
FuseSchool i am extremely sorry..it was today i went through my chapter and the video and you are right. there were 2 moles of HCl for every 1 mole of Ba(OH)2....so it is correct ... 4:41 sorryy
Not a problem!! Happy you managed to work it out!
