Potentials of the Elements and Their Compounds at 25°C. Standard potentials are tabulated except when a solution composition is stated; the latter are formal potentials and the concentrations are in mol/liter. Standard or formal. Solution. Half-reaction potential, V composition. Actinium. Ac3+ + 3e? = Ac. ?2.13. Aluminum.
Greater the oxidation potential of metal, more quickly can it undergo loss of electrons and greater is its reactivity. Thus, a metal with greater oxidation potential can displace metals with lower oxidation potential from their salt solution.

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 . This tendency depends on the magnitude of standard reduction potential. The metal which has high negative value (or smaller positive value) of standard
corrosion had emerged centuries ago and is still in use because of its wide application. CONCLUSION: The electrochemical series helps to pick out substances that are good oxidizing agents and those which are good reducing agents. As the reduction potential increases (negative value decreases), the tendency of the
Standard electrodes and electrochemical series, characteristics and applications. VERY SHORT ANSWER QUESTIONS. 1. What is electrode potential? When a metal is placed in a solution of its ions, the metal acquires either a positive or negative charge with respect to the solution. On account of this, a definite potential.
Electrochemical Series. Now let us solve some numerical problems to understand the applications of this method in calculating standard EMF. 2. Comparison of A prediction about ability of a given metal to produce H2 gas by its reaction with dilute acids can be easily made from the knowledge of electromotive series.
Electrochemical Series of Metals (ESM). Different metals get ionised at different rates. For e.g., metals like sodium when exposed to air combine almost instantly with the oxygen present therein (sodium atom gives up an electron almost as soon as it is in contact with oxygen). On the other hand, metals like gold if exposed to
sic concepts of electrochemistry are presented, with the practical examples of its application in fuel cells, and with the perspective of the history of the subject. 1. – Introduction. Prior to Alessando Volta (fig. 1) and The electrochemical series relates the standard electrode potentials of elements and ions, and is indicative of
7 Dec 2017 Electrochemical series is a series of electrodes or half cells arranged in order of their increasing standard oxidation potentials or in the decreasing.
