The quantity of silver deposited when one coulomb charge is passed through AgNO3 solution: (1) 0.1 g atom of silver (2) 1 chemical equivalent of silver (3) 1 g of silver (4) 1 electrochemical equivalent of silver

1. 0.1 g atom of silver
2. 1 chemical equivalent of silver
3. 1 g of silver
4. 1 electrochemical equivalent of silver

Correct answer: 1 electrochemical equivalent of silver

Solution

The correct option is '1 electrochemical equivalent of silver' because electrochemical equivalent is defined as the mass of a substance deposited or liberated at an electrode during electrolysis when one coulomb of electric charge passes through the solution, which specifically applies to the deposition of silver from AgNO3.
