Standard potential (E cell o ) can be calculated by the following formula.

The elements which are easier to oxidize compared to H2(g) have to be identified.
a)Cu d)Agb)Zn e)Crc)Fe
Concept introduction:
Under certain conditions a cell potential is measured it is called as standard potential (Ecello).
Standard potential (Ecello) can be calculated by the following formula.
Ecello=Ecathodeo-Eanodeo
The Ecello value is positive, the reaction is predicted to be product favoured at equilibrium.
The Ecello value is negative, the reaction is predicted to be reactant favoured at equilibrium.
Electrochemical series:
It is a decreasing order of the reduction potentials. The most positive E0 are placed in the top in the electrochemical series, it has greater tendency for reduction and lower tendency of oxidation. And the most negative E0 values of elements are placed in the bottom of the series.

(d) Concentrated nitric acid is added to a solution of sodium bromide.
(e) Aluminum metal is added to a solution of hydrogen peroxide.
The strongest oxidising agent is
(a) F2
(b) Cl2
(c) I2
