NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
Calculate the total number of electrons transferred when 2 moles of H3PO2 react with excess AgNO3 in the given redox reaction: H3PO2 (aq) + 4 AgNO3 (aq) + 2 H2O(l) → H3PO4 (aq) + 4Ag(s) + 4HNO3 (aq).
A
8 moles
B
4 moles
C
2 moles
D
16 moles
Correct Answer
Option A
Detailed Explanation
In the given reaction, 4 moles of Ag+ are reduced to 4 moles of Ag, meaning 4 moles of electrons are transferred per mole of H3PO2. Therefore, for 2 moles of H3PO2, 8 moles of electrons are transferred.
