R3.1.15 Identify an appropriate indicator for a titration [HL IB Chemistry]

When [In-] = [HIn] then the indicator is at colour change. This should be at equivalence point for the titration. The pH of the equivalence point = pka of the indicator.

I have officially finished all 10 topic playlists to prepare for my dreadful paper 1 and 2 tomorrow. Before I face my doom, just want to thank you so much for these because they have seriously helped me get through the 2 years in chem!

Thank you Mr. Thornley... Your videos are really helpful 😊

Thank you so much! I feel much better about this chapter now. :)

So, it means the PH range should include the PH at equivalent?

Hi Mr. Thornley! :)

Thank you so much for your videos :) I have a question about indicators. Why can you cross out [HIn] and [In-] in the above equation? How do you know that is when the reaction finishes?

Isn't the point where pKa = pH the Half-equivalence point?

Oops 0:53 you put + instead of x Richard

Is there an assumption that the addition of the indicator does not affect the overall pH of the acid/base that it is added to?
