In a galvanic cell, the salt bridge

In a galvanic cell, the salt bridge

Options

  1. ADoes not participate chemically in the cell reaction.
  2. BStops the diffusion of ions from one electrode to another.
  3. CIs necessary for the occurrence of the cell reaction.
  4. DEnsures mixing of the two electrolytic solutions.

Correct answer

A. Does not participate chemically in the cell reaction.

Step-by-step solution

Salt bridge is introduced to keep the solutions of two electrodes separate, such that the ions in electrode donot mix freely with each other. But it cannot stop the process of diffusion.It does not participate in the chemical reaction. However, it is not necessary for occurence of cell reaction, aswe know that designs like lead accumulator, there was no salt bridge, but still reactions takes place.
