Question

2al + 3sn²⁺ → 2al³⁺ + 3sn
in the voltaic cell above, which letter represents the salt bridge?

Explanation:

In a voltaic cell, the salt bridge (containing an electrolyte like NaCl here) connects the two half - cells to maintain electrical neutrality. Looking at the diagram, the part labeled C with NaCl is the structure that connects the two beakers (half - cells) containing Sn and Al solutions, so it represents the salt bridge.

Answer:

C
