State which of these will act as a non-electrolyte

A.Liquid carbon tetrachloride
B.Acetic acid
C.Sodium hydroxide aqueous solution
D.Potassium chloride aqueous solution

Solution

Correct option: (A) Liquid carbon tetrachloride.

Carbon tetrachloride (CCl4) is a covalent compound. Its liquid solution but does not conduct electricity due to the absence of free mobile ions, CCl4 does not conduct electricity and hence it is non-electrolyte.

Acetic acid (CH3COOH), sodium hydroxide (NaOH), and potassium chloride (KCl) can form ions in their aqueous solution and hence they are electrolytes.
