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
