A strong acid is one that is fully ionised in solution.
A strong acid is one that is fully ionised in solution. Sulphuric acid and hydrochloric acid are both strong acids. They break up completely into positive and negative ions in solution. This is a different property to concentration, which refers to the dilution of an acid, normally in water. So an acid can be both strong and concentrated.
