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
n - factor of `H_(3)PO_(3) = 2`
(In oxyacids H-atom directly attached to oxygen are replaceable)
`N = M xx n - "factor " = 0.3 M xx 2 = 0.6 N`
