Question

The correct way of making a solution of acid in water is to

• A. add water to acid.
• B. add acid to water.
• C. mix acid and water simultaneously.
• D. add water to acid in a shallow container.

Answer 1

The correct option is B

add acid to water.

Adding acid to water:

1. If we try to add water to acid it will be an exothermic reaction that will produce a lot of heat which may lead to an explosion.
2. Hence, acid should not be added to water for avoiding any mishappening.
3. While we dilute acid, it is always preferred that the acid is added to water rather than the water being added to the acid
4. As adding water to a concentrated acid releases a huge amount of heat, which can cause an explosion and acid burns on the skin, clothing, and other body parts.
5. Due to this, adding acid to water is naturally safe, but adding water to acid is not safe.

Thus, the correct option is option B.
