The correct formula of salt formed by the neutraliation of hypophosphorous acid with NaOH is

A

`Na_(3)PO_(2)`

B

`Na_(3)PO_(3)`

C

`NaH_(2)PO_(2)`

D

`Na_(2)HPO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Hypophosphorus acid `(H_(3)PO_(2))` is a monobasic acid and hence forms `NaH_(2)PO_(2)` salt.
`H_(3)PO_(2) + NaOH rarr NaH_(2)PO_(2) + H_(2)O`
