Electrochemistry deals with the interaction between electricity and a chemical reaction that either generates electricity or require electricity to react. Electrolyte is an aqueous solution that conducts electricity.
When an electrolyte is dissolved in a solvent, the molecules get separated into two oppositely charged ions and the sum of these charged ions are always equal. Ions move towards oppositely charged electrodes and the process of ionization is reversible. The degree of ionization is affected by the nature of electrolyte ,solvent, dilution and temperature
