Electrochemical cell and Gibbs Energy of the Reaction
Electrochemical cell and Gibbs Energy of the Reaction
Electrical work done in one second is equal to electrical potential multiplied by total charge passed. If...
Nernst Equation
Nernst Equation
It relates electrode potential with the concentration of ions. Thus, the reduction potential increases with the increase in the concentration of ions. For...
Kohlrausch’s Law
Kohlrausch’s Law
It states that the limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of the anion...
Conductance, Conductivity, Molar & Equivalent Conductivity
Conductance (G)
It is the reciprocal of resistance and may be defined as the ease with which the electric current flows through a conductor.
SI unit...
Corrosion
Corrosion
It involves a redox reaction and formation of an electrochemical cell on the surface of iron or any other metal. At one location oxidation...
Fuel Cells
Fuel Cells
A fuel cell differs from an ordinary battery in the sense that the reactants are not contained inside the cell but are externally...
Batteries
Batteries:
When Galvanic cells are connected in series to obtain a higher voltage the arrangement is called Battery.
Primary Batteries:
Primary cells are those which can be...
Quantitative Aspects of Electrolysis
Michael Faraday was the first scientist who described the quantitative aspects of electrolysis. Faraday published his results during 1833-34 in the form of the...
Electrochemistry, Electrochemical Cells and Types
Electrochemistry
Electrochemistry is the study of the production of electricity from the energy released during a spontaneous chemical reaction and the use of electrical energy...
