What is electrochemistry?

Electrochemistry is the study of chemical reactions in which movement of electron happen.

An electrolytic cell is the cell in oxidation and reduction occurs.

It's all about how electrical energy interacts with chemical transformation.

For example, is concerned with the study of electrochemical cells. It is concerned with cells that convert chemical to electrical energy.

Thus, the correct matches are a. 3. Galvanic cell.

b. 1. Cathode.

c. 2. Anode.

d. 5. Electrolytic cell.

e. 4. Half reaction.
