Which of the following substances forms a neutral solution when dissolved in water?
Answer and explanation
Correct answer: Sodium chloride
Sodium chloride is formed from hydrochloric acid, a strong acid, and sodium hydroxide, a strong base. Their ions do not undergo significant hydrolysis in water, so sodium chloride produces an approximately neutral solution; option A is correct. Hydrochloric acid is acidic, sodium hydroxide is basic, and ammonium chloride generally gives an acidic solution because of the ammonium ion.
