Why does `H_(3)PO_(3)` act as a reducing agent but `H_(3)PO_(4)` does not ?

Text Solution

Verified by Experts

`H_(3)PO_(2)` (hypophosphorus acid) acts as monobasic acid because it has only one replaceable hydrogen atom present as OH group which it can easily release.
`underset("Hypophosphorus acid")(H_(3)PO_(2)+NaOH) to underset("Sod. Hypophosphite")(NaH_(2)PO_(2)+H_(2)O)`
