Correct answer: A→P,Q; B→Q,R; C→R,S; D→T. - (A) is an ionic solid, hence a true electrolyte (P). It completely dissociates in water, thus acting as a strong electrolyte (Q).
- (B) is a covalent gas but completely dissociates into ions in water, so it is a potential electrolyte (R) and strong electrolyte (Q).
- (C) CH3COOH is a covalent liquid (R) and partially dissociates in water, thus acting as a weak electrolyte (S).
- (D) CrCl3 . 3 is a neutral coordination complex [Cr()3Cl3] which does not ionize in water, hence a non-electrolyte (T).
