Boojho added dilute sulphuric acidto lime water. Will the reaction mixturebecome hot or cool?

The reaction between dilute sulphuric acid and lime water (calcium hydroxide) is an exothermic reaction. This means it releases heat. Therefore, the reaction mixture will become hot.

Here are the steps of the reaction:

1. Boojho adds dilute sulphuric acid to lime water.

2. The sulphuric acid (H2SO4) reacts with the lime water (Ca(OH)2) to produce calcium sulfate (CaSO4) and water (H2O).

3. This reaction releases heat, so the mixture becomes hot.

The chemical equation for this reaction is:

H2SO4 (aq) + Ca(OH)2 (aq) → CaSO4 (s) + 2H2O (l)

The "(aq)" denotes an aqueous solution, "(s)" denotes a solid, and "(l)" denotes a liquid. The arrow indicates the direction of the reaction, from reactants to products.
