If we're carrying out an acid -based titration, then let's say we start with a weak acid or even a strong acid represented as ha, and we add a strong base represented as hydroxide.
00:14
The reaction will produce the conjugate base of the acid plus water.
00:22
At the equivalence point, if we are monitoring ph, we're going to see something like this, this being our equivalence point volume.
00:37
And ph and at the equivalence point we would have added moles of hydroxide that are equal to moles ha at the equivalence point.
01:00
The ph will depend on whether or not we have a weak acid or a strong acid and it'll also depend on whether or not we're doing an acid titration by adding a base or doing a base titration by adding an acid.
01:19
So we really can't say anything universal about the ph at the equivalence point.
01:27
A then says the ph is at its highest value for any reaction at the equivalence point.
01:35
No, obviously not.
01:37
As we can see, the ph increases later on.
01:40
And if we were to do a base being titrated with a strong acid, at the equivalence point, it's still not the highest ph...
