To neutralize completely 20 mL of 0.1M aqueous solution of phosphorus acid `(H_(3)PO_(3))` the volume of `0.1M` aqueous KOH solution required is

Text Solution

Verified by Experts

The correct Answer is:
40
`H_3PO_3` is dibasic while KOH is mono- acidic `n_aM_aV_a=n_bM_bV_b`
`2xx0.1 xx20 = 1 xx0.1 xx V_b` or `V_b = 40 mL`
