Which salt gives a nearly neutral solution because it is formed from a strong acid and a strong base?
Answer and explanation
Correct answer: Sodium chloride
The relevant principle is the relation between salt hydrolysis and the strengths of the parent acid and base. Sodium chloride is produced by the reaction of strong hydrochloric acid with strong sodium hydroxide: HCl + NaOH → NaCl + H₂O. Neither ion undergoes significant hydrolysis, so its aqueous solution is approximately neutral. Ammonium chloride is acidic, while carbonate and hydrogen carbonate salts are basic. Therefore, option C is correct.
