Mixing an acid or base with water results in increase in the concentration of ions (H3O +/OH – ) per unit volume.

Question

Write true or false for the following statements:

Mixing an acid or base with water results in increase in the concentration of ions (H3O⁺/OH^– ) per unit volume.

Answer 1

True

If water is added slowly to the acid with constant stirring then the heat generated may cause the mixture to splash out and cause burns. Hence, care must be taken while mixing concentrated nitric acid or sulphuric acid with water. The acid must always be added slowly to the water with constant stirring.
