Question

What happenswhen an acid or base is added to the water why does the beaker appear warm why should we always add acid or base to the water and not water to the acid or base?

Answer 1

Answer:

We should always add acid or base to water.

Explanation:

The acid or base should be added slowly to water with constant stirring.

When a acid or base are added to water , results in decrease in the concentration of ions i.e H3O+ or OH- per unit volume. This process is dilution. The acid or base is diluted.

It is a exothermic reaction, lot of heat energy is released during the process. So the beaker becomes hot.

If water is added to acid or base, the heat energy generated may cause the mixture to splash out and cause burns. The glass container may break due to local heating. So , we should add acid or Base to water.

Hope this helps you
