NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): In the reaction H3PO2 (aq) + 4 AgNO3 (aq) + 2 H2O(l) → H3PO4 (aq) + 4Ag(s) + 4HNO3 (aq), H3PO2 acts as a reducing agent.
Reason (R): H3PO2 donates electrons to Ag+ ions, reducing them to metallic silver.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
H3PO2 is oxidized to H3PO4, donating electrons to Ag+ ions, reducing them to Ag. This makes H3PO2 a reducing agent.
