Question

A solution of sodium chloride will turn :

• A. red litmus blue
• B. blue litmus red
• C. red litmus orange
• D. no change in colour of either red or blue litmus

Answer 1

Answer: (D)

no change in colour of either red or blue litmus

Sodium chloride is a salt and an ionic compound and neither base nor an acid so cannot change the color of the litmus paper. The attraction between sodium and chloride ion in the solid is strong that only highly polar solvents like water dissolve sodium chloride well.
