Question

A substance 'A' releases hydrogen ions and a substance 'B' releases hydroxide ions in their respective aqueous solution. What will be the products formed if A and B react with each other?

• A. Water
• B. Carbon dioxide
• C. Hydrogen
• D. Salt

Answer 1

Answer: (A), (D)

The correct options are
A Water
D Salt

Acids are substances which release hydrogen ${\text{H}}^{+}\text{(aq)}$ ions in water and bases are substances which release hydroxide ${\text{OH}}^{-}\text{(aq)}$ ions in water.

Acid reacts with a base to form salt and water, and this reaction is called a neutralisation reaction. The general representation of this reaction is given below:

$\text{Acid (aq) + Base (aq)}\to \text{Salt (aq) + Water (l)}$

So, the products obtained are salt and water.
