Which of the following will dissociate in aqueous solution, to give a positive ion other than hydronium ion, and a negative ion other than hydroxyl ion?

NaCl

Reason — NaCl dissociates in water into positive ion Na⁺ other than hydronium ion, and a negative ion Cl^- other than hydroxyl ion. Whereas, KOH gives hydroxyl ion and HCl and CH₃COOH gives hydronium ion in water.
