Question

Standard electrode potential and electrochemical series and their application

Answer 1

Answer:

Electrochemical Series:

A series of electrodes or half cells arranged in order of their increasing standard oxidation potentials or in the decreasing order of their standard reduction potentials is called as electromotive force series or electrochemical series.

Electrochemical series is also known as e.m.f. series

Answer 2

Answer:

Applications of Electrochemical Series. (i) Reactivity of metals: The activity of the metal depends on its tendency to lose electron or electrons, i.e., tendency to form cation . ... (a) Alkali metals and alkaline earth metals having high negative values of standard reduction potentials are chemically active.
