Question

Which of the following is not a characteristic feature of a salt bridge?

(a) Salt bridge joins the two halves of an electrochemical cell

(b) It completes the inner circuit

(c) It is filled with a salt solution (or gel)

(d) It does not maintain electrical neutrality of the electrolytic solutions of the half-cells

I got this question by my college director while I was bunking the class.

This is a very interesting question from Electrochemical Cells topic in portion Electrochemistry of Chemistry – Class 12

Answer 1

The correct answer is (d) It does not maintain electrical neutrality of the electrolytic solutions of the half-cells

For explanation I would say: A salt bridge is a junction that connects the anodic and cathodic compartments in a cell or electrolytic solution. It maintains electrical neutrality within the internal circuit, preventing the cell from rapidly running its reaction to equilibrium.
