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

A

40 mL

B

20 mL

C

10 mL

D

60 mL

Text Solution

Verified by Experts

The correct Answer is:
A
`H_3PO_3` is a dibasic acid
`N_1V_1` (acid) = `N_2V_2` (base)
` 0.1xx2xx20 = 0.1xx1xxV_2`
`:. V_2 = (0.1 xx2 xx20)/(0.1 xx1) = 40 ` mL
