Question

Aqueous solution of which salt tirns red litmus to blue

Answer 1

Answer:

Potassium carbonate

Potassium carbonate (K2CO3) is formed from a weak acid, carbonic acid (H2CO3), and a strong base, potassium hydroxide (KOH). On hydrolysis, K2CO3 forms more OH- ions than H+ ions. Thus, it is basic and therefore turns red litmus blue.
