Question

Consider the statement
$S_1$ : In electrochemical cell which contain $Ag$ cathode and $Pb$ anode, $KCl$ cannot used as salt bridge
$S_2$ : Salt bridge maintain the electrical neutrility
$S_3$ : For a concentration cell $\Delta G^{\circ }$ is zero
Select the correct statement.

• A. $S_1,S_2$ and $S_3$
• B. Only $S_1$
• C. Only $S_2$
• D. Only $S_2$ and $S_3$

Answer 1

The correct option is A $S_1,S_2$ and $S_3$

In electrochemical cell which contain $Ag$ cathode and $Pb$ anode, $KCl$ cannot used as salt bridge.
Salt bridge maintain the electrical neutrility.
For a concentration cell $\Delta G^{\circ }$ is zero.
