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 0.1M`H_(3),PO_(4)`, does not form a buffer

A

50 ml

B

150 ml

C

200 ml

D

250 ml

Text Solution

Verified by Experts

The correct Answer is:
C
In the above question if we used 200 ml, 0.1 M NaOH, only salt `Na_2HPO_4` is formed
