Question

hey can anyone explain to me the principle behind working of electrolysis? i seem to have forgotten it.

Answer 1

please draw a diagram too..

Answer 2

electrical energy is converted to chemical energy as we use current to carry out a non spontaneous reaction

Answer 3

Process of electrolysis

The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The required products of electrolysis are in some different physical state from the electrolyte and can be removed by some physical processes. For example, in the electrolysis of brine to produce hydrogen and chlorine, the products are gaseous. These gaseous products bubble from the electrolyte and are collected.[2]
2 NaCl + 2 H2O → 2 NaOH + H2 + Cl2
A liquid containing mobile ions (electrolyte) is produced by
Solvation or reaction of an ionic compound with a solvent (such as water) to produce mobile ions
An ionic compound is melted (fused) by heating

An electrical potential is applied across a pair of electrodes immersed in the electrolyte.

Each electrode attracts ions that are of the opposite charge. Positively charged ions (cations) move towards the electron-providing (negative) cathode, whereas negatively charged ions (anions) move towards the positive anode.

At the electrodes, electrons are absorbed or released by the atoms and ions. Those atoms that gain or lose electrons to become charged ions pass into the electrolyte. Those ions that gain or lose electrons to become uncharged atoms separate from the electrolyte. The formation of uncharged atoms from ions is called discharging.

The energy required to cause the ions to migrate to the electrodes, and the energy to cause the change in ionic state, is provided by the external source of electrical potential.
u can ask me if u dint understand
the concept being run current trough the electrolyte to get neutal atoms deposited at the cathode and anode(after becoming neutal) and rest of the charged ions remain in the solution
