Question

Write two applications of electrochemical series?

Answer 1

Application of electrochemical series:

1. To determine the reactivity order of elements. Example: metals with low reduction potential will be more reactive and will liberate $H_2$ from acid solution.

2. It can determine the feasibility of a redox reaction. Thereby, helps in constructing an electrochemical cell as reduction potential of cathode electrode should be higher than of anode material.
