Oxoacids of phosphorus which contain P - H bond act as reducing agents and reduce metal salts to free metals. Thus, H 3 PO 2 act as reducing agent while H 3 PO 4 does not.

Q. Assertion : $H_{3} P O_{2}$ has strong reducing property but $H_{3} P O_{4}$ does not.
Reason : $P - O H$ bond present in $H_{3} P O_{4}$ .

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Oxoacids of phosphorus which contain $P - H$ bond act as reducing agents and reduce metal salts to free metals. Thus, $H_{3} P O_{2}$ act as reducing agent while $H_{3} P O_{4}$ does not.
