Question

Distinguish between strong electrolyte and weak electrolyte.

Answer 1

	Strong electrolyte	Weak electrolyte
1.	The electrolytes ionizing completely or almost completely are strong electrolytes.	The electrolytes which dissociate to a smaller extent in aqueous solution are weak electrolytes
2.	In strong electrolytes, there is no equilibrium between the ions and the nonionized molecules.	In weak electrolytes, an equilibrium exists between the ions and the nonionized molecules.
3.	A reaction arrow (→) between the ions and nonionized molecules of the strong electrolyte is used to represent the ionization reaction	A double arrow (⇌) between the ions and nonionized molecules of the weak electrolyte is used to represent the ionization reaction.
4.	e.g. Strong acids, strong bases and salts.	e.g. Weak acids and weak bases
