all formulas of electrochemistry
How are electrochemical reactions in water analyzed?
Electrochemical reactions in water are better analyzed by using the ion-electron method, where H +, OH − ion, H 2 O and electrons (to compensate the oxidation changes) are added to the cell's half-reactions for oxidation and reduction. In acidic medium, H + ions and water are added to balance each half-reaction .
What is electrochemistry in chemistry?
Electrochemistry is the study of chemical processes which lead to electrons moving. This movement of electrons is called electricity, which can be generated in a reaction known as an oxidation-reduction reaction by electrons from one element to another.

Who invented electrochemistry?
English chemist John Daniell ( left) and physicist Michael Faraday ( right ), both credited as founders of electrochemistry. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change.
What are the two types of electrochemical cells?
There are two types of electrochemical cells: galvanic, also called Voltaic, and electrolytic. Galvanic cells derives its energy from spontaneous redox reactions, while electrolytic cells involve non-spontaneous reactions and thus require an external electron source like a DC battery or an AC power source.
Nernst Equation
Dependence of electrode potential and EMF on concentration and temperature. For electrode potential; For solids, liquids or gases at 1 atom. byjus.com
Gibbs Free Energy Change
Gibbs free energy change in an electrochemical reaction can be expressed as the equivalent of the potential difference. byjus.com
Concentration Cell
Concentration cells are electrochemical cells in which the emf arises from a transfer of material from one electrode to another due to a concentration difference between the two. In general for concentration cells. byjus.com
Electrolysis
The process of decomposition of an electrolyte by the passage of electricity through its aqueous solution or molten state. Electrodes used in the electrolysis of different electrolytes are of two types, inert electrodes and active electrodes. byjus.com
Faraday First Law of Electrolysis
The mass of primary products formed at an electrode by electrolysis is directly proportional to the quantity of electricity passed. byjus.com
Faraday Second Law of Electrolysis
The masses of different primary products formed by equal amounts of electricity are proportional to the ratio of molar mass to the number of electrons involved with a particular reaction. byjus.com
Conductance
In relation to electrolytes, the term conductance (C) is used more frequently than resistance. Conductance implies the case with which electric current can flow through a conductor. It is defined as the reciprocal of resistance. byjus.com
Kohlrausch Law
The molar conductivity of an electrolyte at infinite dilution can be expressed as the sum of the ionic conductivities of cations and anions each multiplied by the number of ions present in one formula unit of the electrolyte. byjus.com
Applications of Kohlrausch Law
1. In the calculation of molar conductivity at infinite dilution for a weak electrolyte. 2. In the calculation of the degree of dissociation. 3. In the calculation of solubility of a sparingly soluble salt. As the solution is saturated but infinitely dilute. Molarity = solubility Hence, Where ‘u’ are ionic mobilities at infinite dilution.
