What is pH of a salt solution?
And thus for strong acids mixed with 1 equiv of strong base we get....
Because neither chloride nor perchlorate is particularly basic (they are the conjugate bases of strong acids, and thus they do not compete strongly for the protium ion), the
On the other hand, when 1 equiv acetic acid, a WEAK acid, is treated with 1 equiv of sodium hydroxide, the resultant solution is stoichiometric in
And thus at equivalence, the
