The normality of 0.3 M phosphorous acid ...

The normality of `0.3 M` phosphorous acid `(H_(3) PO_(3))` is

A

(a)0.1

B

(b)0.9

C

(c )0.3

D

(d)0.6

Text Solution

Verified by Experts

The correct Answer is:
D
`H_(3)PO_(3)` is a dibasic acid and thus its molecular weight `=2xx "equivalent" wt`.
`:. 1 M=2N`
Hence, `0.3 M=2xx0.3=0.6 N`
