Thank you for clear explanation and showing how to exactly carry out the procedure... all in just under 5 mins. Helped me a lot with my AS chemistry exam!!

[@farhantanvirfaruque5544]

When did you take your AS exams?
I have IAS Unit 3 exam tomorrow and I must say this video is "perfection" !!!

[@a.human.]

@@farhantanvirfaruque5544 I was talking about mock exams.
I have IAS Chemistry unit 3 exams tomorrow too. All the best.

[@farhantanvirfaruque5544]

Same to you, bro :)

[@farhantanvirfaruque5544]

@@a.human. How was your exam?
Do you have physics too?

[@nycdrillcc2198]

as a student of ACG Strathallan this video has really developed a better understanding of Titrations in Chemistry, Thanks for this masterpiece of a video :) Cheers

WHAT A VIDEO, ABSOLUTELY FAB!

She doesnt explain why she's doing things only what she's doing.

Why not the acid in the burette?

[@faithbiccum9526]

to all the haters...pay attention to the content, she obviously way smarter than many of us, be kind :)

Why does she remind me of Sid the sloth

ouch

lmaooo

[@DanDAlittleMan]

lol, oof

[@DanDAlittleMan]

i can't stop thinking bout that now, thanks

[@tic9563]

We saw her last week too and I said the exact same thing oml

[@abdulmzaki]

Doesnt adding distilled water to the HCl acid when the nozzle of the burette is being cleaned change the concentration of the acid. Which will in turn change the indicator colour, ruining the results, someone explain this to me pls

[@myarparekh5499]

Adding water to HCl won't make it more or less concentrated- it will be more diluted but it's the amount of HCl (acid) that make an acid more or less concentrated. So it wont affect the results if you add water. Hope this helps😊

[@naaokailey7030]

@@myarparekh5499 Thank you very much for the explanation!!

[@Devils.Advocate20]

@@myarparekh5499 If concentration is the number of moles in a given volume and since adding water will increase the volume the concentration will decrease. pH is related to the concentration of H+ so the pH will be affected. Like OP I still don’t understand why she added distilled water.

[@Devils.Advocate20]

@@myarparekh5499 Everything you said was wrong

[@Cloudy.419]

@@Devils.Advocate20 what's the correct answer than?

[@aesthetic_disney_1239]

thanks for the video! why do you only rinse the conical flask with distilled water, and not the alkali/acid too?

[@rayz5181]

Adding excess acid or alkali will affect the concentration of HCl you work out in the end. Using distilled water makes more sense since it ensures all of the acid and alkali react. Note that distilled water will not affect the moles of the solution.

your thoughts

[@iambored3583]

How would we calculate the concentration since we don't know anything besides the volume of both the solutions

[@epicswag6771]

You have the concentration of Na2CO3 and you have the equation
