6.1 Properties of Electrolytes and Non-electrolytes

Electrolytes and Non-electrolytes
■ Electrolyte

	►	A compound that only conducts electricity when molten dissolved in water.
	►	Contain ions which move freely to carry electrical charges.
	►	Undergoes decomposition to the elements when an electric current flows through.
	►	Examples : ○ Oxides and hydroxides of metals in the molten state or aqueous solution (if insoluble). ○ Aqueous solutions of mineral acids.

■ Non-electrolyte

	►	A compound that does not conduct electricity, whether in solid, molten or aqueous solution.
	►	No ions which can carry electrical charges.
	►	No change when an electric current flows through.
	►	Examples : All covalent compounds such naphthalene, sugar, benzene and others.
