Solution
The salt which will give an acidic solution on dissolving in water is NH4Cl.
Explanation:
The Ammonium chloride (NH4Cl) is a salt formed from a strong acid (HCl) and a weak base (NH4OH). When dissolved in water, the ammonium ion undergoes cationic hydrolysis to release extra hydrogen ions, which lowers the pH and makes the solution acidic
