Question

1. Which of the following statements about salt bridges is incorrect?

		Salt bridges help keep electrical neutrality in the solutions
		Salt bridges transport electrons from one half reaction to another
		Salt bridges complete the electrical circuit
		A voltaic cell will not function without a salt bridge

Answer 1

The purpose of a salt bridge is not to move electrons from the electrolyte, rather to maintain charge balance because the electrons are moving from one half cell to the other.

Without the salt bridge, the solution in the anode compartment would become positively charged and the solution in the cathode compartment would become negatively charged,because of the charge imbalance,the electrode reaction would quickly come to a halt,therefore It helps to maintain the flow of electrons from the oxidation half cell to a reduction half cell.

2nd OPTION IS INCORRECT
