Some water evaporates from a dilute solution of sulfuric acid. No sulfuric acid is lost. Sulfuric acid is a strong acid.
Which statement describes what happens to the concentration and ionisation of the acid?
The amount of acid per dm3\text{dm}^3dm3 decreases, and the sulfuric acid remains fully ionised.
The amount of acid per dm3\text{dm}^3dm3 increases, and the sulfuric acid becomes more strongly ionised.
The amount of acid per dm3\text{dm}^3dm3 increases, and the sulfuric acid becomes partially ionised.
The amount of acid per dm3\text{dm}^3dm3 increases, and the sulfuric acid remains fully ionised.
