Question

The correct way of making a solution of an 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

When water is added to a concentrated acid the reaction is exothermic and the amount of heat generated may cause the mixture to splash out and cause burns. On the other hand, when the acid is added to water slowly with constant stirring, the mixture will not splash out as the amount of heat generated is less.
