1.	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 Which of the following volume of 0.1 M NaOH added to 100 mlof 0.1MH_(3),PO_(4), does not form a buffer
Answer» 50 ml 150 ml 200 ml 250ml SOLUTION :In the above question if we USED 200 ml, 0.1 MNaOH, only SALT`Na_2HPO_4` is formed
