An electrolyte is a substance that conducts electric current either in molten or aqueous form.
Electrolytes dissociate in water to produce ions that are responsible for conduction of electricity. Examples are bases such as NaOH, KOH and acids such as HCl and HNO₃.
Non-electrolytes on the other hand do not conduct electricity since they do not ionize while dissolved in water.
They include, organic compounds such as glucose, sucrose, among others.
