A solution containing a weak acid and its conjugate acts as an acidic buffer. In a buffer the dissociation of the well acid is suppressed by its conjugate base. `(K_(1),K_(2),` and `K_(3),` of `H_(3)PO_(4)`, are `10_(-4), 10^(-4), 10^(-13)` respectively
What is the `P^(H)` of a solution obtained by mixing 100ml of `0.1 MH(3) PO_(4)`, and 150ml of 0.IM NaOH
