its the equivalence point;Ka or Kb

Are you positive about that? I was sure that pH was equal to the pKa, therefore it would indicate a change...

I thought the same thing until I put that answer in and got it wrong :(

And that's the answer that it gave you in response?

anonymous · Answer

Yeah it said pH indicators change color at their equivalence point. The pH at which the color change happens for a particular indicator molecule depends on it's Ka or Kb.
