## Question:

Determine the mass of copper that is plated out when a current of 10.0 A is passed for 30.0 minutes through a solution of copper (ii) nitrate.

## Electrochemical Cell:

An electrochemical cell can be considered as an overall oxidation-reduction (redox) reaction, where the oxidation and reduction half-reactions exist in separate anode and cathode half-cells respectively. The simplest half-cell design involves a solid metal electrode immersed in an aqueous solution containing a salt compound of the metal cation. These solid metal portions are connected by a wire to allow the flow of electrons. An internal salt bridge or porous membrane allows passage of salt ions between the solutions to maintain electrical neutrality. An electrochemical cell reaction may occur spontaneously or non-spontaneously at the given cell conditions. These are known as voltaic (galvanic) and electrolytic cells respectively.
