Two electrodes in electrolyte solutions
Chat with our AI personalities
A galvanic cell consists of two half-cells connected by a salt bridge or a porous barrier. Each half-cell typically contains a metal electrode in contact with an electrolyte solution. The two half-cells undergo redox reactions, producing an electric current.
The voltaic cell
Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
An electrolytic cell
Mg(s) Epi-Boii
A cell with a negative voltage charge.
