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 :

Adding water to acids release energy. We can experience it by touching at test tube (it becomes hot), sometimes the heat is too large to handle and glasses of container or test tube may explode and acid can spill over. So we always take water in excess and drop acid drop by drop, so that heat produced can be cooled down by this water and accidents can be prevented.
