To construct the galvanic cell illustrated above, the salt bridge was prepared by soaking a piece of cotton in 5.0MNaNO3(aq) before placing it inside the U-shaped tube filled with distilled water. If the cotton was soaked in distilled water by mistake, which of the following best explains how the operation of the cell would be affected

Respuesta :

Answer:

The cell reaction reaches equilibrium quickly and the cell emf becomes zero.

Explanation:

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

A solution of a salt that dissociates easily is normally used. Water is ineffective at functioning as a salt bridge. Hence the effect stated in the answer.

The operation of cell has been affected by the cell at equilibrium with emf equal been zero.

The galvanic cell has been an electrochemical cell, that has been generating reaction with the electric current. The electric current has been passed through the samples with the application of salt bridge.

Salt Bridge in Galvanic cell

The salt bridge has been function to transmit  has electrons for the flow of current. The addition of distilled water in the salt bridge has been limiting the salts for the transmission of electrons.

Thus, the operation of the cell has been affected by the cell at equilibrium with emf equal been zero.
