Chemistry | Acids and Bases | 8-mark questions (Back titration)
How to answer those long 8 marks questions on Acids and Bases? Well, here's a quick lesson on how to approach them...
This is called back titration. For those of you in Matric (Grade 12) or University, this lesson will be really helpful.
Enjoy

So yesterday I was on your stoichiometry Playlist starting with 6muffins,was like"oh sir are u kidding?!so now we are baking"🤣🤣but it assisted me a lot because I paused this vid tried it on my own nd and I got it ryt... U rock sir, big time!!!!

I know right... 😂. I try to make my examples very relatable. Look at you now, a whole champion on Stoichiometry. Thank you very much showing appreciation
Thank you so much sir❤these 8 mark questions always scared me, but now I see how simple it is.

sir thank you so much I watched your videos on stochiometry nearly the whole day before I came to try this question( I never tried back titration ever) and with one try I got it right the steps everything
What a question, what a teacher!

Great video as always 🔥 So sir, I can choose to use the titration formula or basic stoichiometry calculations depending on which I prefer?

So if i react NaOH with something and some NaOH remains after that. Does the concentration remain the same? And if yes, why does it remain the same?

I always make an example with Oros (my favourite summer drink, yummy!!!). Suppose you make a mixture into a jug... Does the taste change as you use it? No... The taste is concentration.
Sir based on stoichiometry why did u calculate the volume of nitric acid whereas they already gave us?
Thank you💗☺
Thank you very much I understand now 😭, these 8 mark questions are really tough. But do you mind doing another one?🙏

why didn't you convert the 35cm^3 to dm^3 in the titration step at @10:28 ?

Hi sir. How do we know that the 0.04 mol of nitric acid is the total amount of mols ?
