Answer 2

Answer:

Electrochemical series is a series of chemical elements arranged in order of their standard electrode potentials.

The hydrogen electrode

H+(aq) + e- →← 1/2H2(g)

is taken as having zero electrode potential. An electrode potential is, by definition, a reduction potential.

Elements that have a greater tendency than hydrogen to lose electrons to their solution are taken as electropositive; those that gain electrons from their solution are below hydrogen in the series and are called electronegative.

The series shows the order in which metals replace one another from their salts; electropositive metals will replace hydrogen from acids.
