WebSo, we're at the equivalence point, but this is a titration of a weak acid with a strong base. And so, we have a basic salt solution at the equivalence point. So, our pH is in the basic range. It's above seven. So, let's find that point on our titration curve. So, we've added here 200 mL of our base. And the pH was 8.67. WebRule of thumb is: Weak acids have strong conjugate bases, while weak bases have strong conjugate acids. As shown in the above two reactions, if HA is a weak acid, then its …
