Why KCl cannot be used as an electrolyte in salt bridge in case of silver electrode? Is that true for lead electrode also?

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.

IT CONTAINS INERT ELECTROLYTE ALWAYS..

HOPE IT HELPS
