Question

Which one of the following would be classified as strong electrolyte?

• A. Benzoic acid
• B. Water
• C. Hydrofluoric acide
• D. Postassium chloride
• E. Glucose

Answer 1

The correct option is D Postassium chloride

Postassium chloride would be classified as strong electrolyte. It completely dissociates into aqueous solution into constituent ions.
$KCl\to K^{+}+C{l}^{-}$
Benzoic acid and Hydrofluoric acid are weak electrolytes. They partly dissociate into aqueous solution.
Water and Glucose are non eectrolytes. They do not undergo dissociation.
