Which of the following substances does not change the colour of either red or blue litmus paper in an aqueous solution?

Answer and explanation

Correct answer: Sodium chloride

The governing idea is the litmus test for acidic, basic and neutral solutions. An aqueous solution of sodium chloride, formed from a strong acid and a strong base, is generally neutral and therefore does not change either red or blue litmus. Hydrochloric acid turns blue litmus red, whereas sodium hydroxide and calcium hydroxide turn red litmus blue. Hence, option C is correct.
