The normality of 0.3 M phosphorous acid ...

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

A

0.1

B

0.9

C

0.3

D

0.6

Text Solution

Verified by Experts

The correct Answer is:
D
`HO-underset(H_(3)PO_(3))underset(H)underset(|)overset(O)overset(||)(P)-OH`
Only hydrogens attached to oxygen and contirute to basicity replaceable. From structure it is clear that phosphours acid, `H_(3) PO_(3)`, is dibasic.
Normality = Molarity `xx` Basicity (for an acid)
`N = 0.3 xx 2 = 0.6`
