Question

Give reason:

While diluting an acid, it is recommended that the acid should be added to water.

Answer 1

1. While diluting an acid, the acid should be added to water because the process is highly exothermic (releases heat).
2. If water is added to concentrated acid, the sudden heat can cause the mixture to splash or boil violently, leading to burns. Adding acid slowly to water allows the heat to be safely absorbed.
