This is a great video. I have a question though. I don’t really understand what you’d add if the weak acid was a diprotic acid (H2A). Because its salt ion would be A^(-2). But then you wouldn’t be able to call that its conjugate base because a conjugate acid-base pair consists of molecules that can be formed from each other by a transfer of a single proton. Diprotic molecules have a transfer of two protons in their buffer system equilibrium.
So what salt do we add to make the conjugate base?
