Re: Conjugate Seesaw

A strong acid wants to completely dissociate, so it makes sense that the conjugate base would be weak because it is unfavorable for it to form more of the strong acid. The same is true for strong bases. It would be unfavorable for the conjugate acid to form the strong base.

Re: pH values of weak and strong acids

Because weak acids do not dissociate completely, some concentration of a weak acid would produce less H3O+ than the same concentration of a strong acid. Therefore, the concentration of H3O+ will be lower with the weak acid, so the pH will be higher.
