Question

A voltaic electrochemical cell is constructed in which the anode is a Cr³⁺, Cr²⁺ half cell and the cathode is a Cl₂Cl^- half cell. The half-cell compartments are connected by a salt bridge.

Write the anode reaction.

Write the cathode reaction.

Write the net cell reaction.

In the external circuit, electrons migrate the Cr³⁺, Cr²⁺ electrode the Cl₂Cl^- electrode.

In the salt bridge, anions migrate the Cr³⁺, Cr²⁺ compartment the Cl₂Cl^- compartment.

Balance the reaction between Al* and Ni²* to form Al and NiO, in acidic solution. When you have
balanced the equation using the smallest integers possible, enter the coefficients of the species shown.
