उत्तर
The salt whose aqueous solution will have no effect on either red litmus or blue litmus is potassium sulphate.
Explanation:
Potassium sulphate (K2SO4) is formed from a strong acid, sulphuric acid (H2SO4), and a strong base, potassium hydroxide (KOH). On dissolving in water, K2SO4 hydrolyses to form equal amounts of H+ and OH− ions. As the salt solution of K2SO4 is neutral, it has no effect on red or blue litmus paper.
