What is the correct way of making a solution of an acid in water?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Add the acid to water
Mixing a concentrated acid with water is highly exothermic. The acid must be added slowly to water with constant stirring, so the heat spreads through the large amount of water. If water is added to the acid, the heat produced can make the mixture splash out, and the glass container may break from the local heating.
