What is an electrolyte?
In Chemistry, electrolyte is defined as a substance or medium that can conduct electricity or electrical charges.
In general, an electrolyte can be ionic compound or covalent compound that act as solute and produce ions upon dissolving in a liquid such as water.
Chemically, when ions dissociate they move across the solution and conduct electricity.
Most common examples of electrolytes are salts, bases and acids that splits up into ions when added to a polar substance e.g. water.
