Question

can we use KCl as electrolyte in the salt bridge of the cell

Answer 1

The KCl-bridge cannot be used when any salt of lead, or silver is used in the cell because lead chloride and silver chloride are insoluble in water. ... A salt bridge is a low resistance device, which establishes an electrical contact between two electrolytes not in direct contact.

Answer 2

Answer:

yes

Explanation:

We can use KCl normally

KCl is used as salt bridge because it provides positive K+ ions and negative Cl- ions as the salt bridge needs to maintain the neutrality in the system by providing enough negative ions equal to the positive ions during oxidation.

but

The KCl-bridge cannot be used when any salt of lead, or silver is used in the cell because lead chloride and silver chloride are insoluble in water.

Yes,, this thing is true for lead electrode as well..

A salt bridge is a low resistance device, which establishes an electrical contact between two electrolytes not in direct contact. This is used to overcome the direct liquid-liquid junction that leads to intermixing. The salt bridge consists of a glass U-tube filled with KCl containing Agar-Agar paste, which sets into a gel.
