Upon titrating a solution of weak monoprotic acid with a weak monoacidic base solution at equivalent point:

Answer»

`pH` in general weak would increase if both solution are first diluted to `10` times the original volume & then TITRATION is carries out
`pH` in general would DECREASE if both solution are first diluted to `10` times the original volume & then titration is carried out.
`pH` in general would remain same `(=7)` if both solutions are first diluted to `10` times the original volumes & then titration is carried out
`pH` in general coule be less than , greater then or equal to `7`if both solutions are first diluted to`10` times the original volume & then titration is carried out.

Solution :Salt of `WA-WB` formed at equivalence point has `pH` independent of concentration and depends on `pK_(a)` and `pK_(b)` of `WA` and `WB` respectively.
