Define strong and weak electrolytes.

Open in App

Solution

Strong electrolytes break apart completely into ions in their aqueous or molten state. They contain mostly ions in their solutions. Sodium chloride, lead bromide, sodium hydroxide, nitric acid, sulphuric acid, hydrochloric acid etc., are some examples of strong electrolytes.

Weak electrolytes partially break apart into ions in their solutions. Ammonium hydroxide, acetic acid etc., are some examples of weak electrolytes.
