Acid with values less than one are considered weak. A strong acid is one which is virtually 100 ionised in solution. Strong acids like HCl or HNO 3 are such good proton donors that none of their own molecules can remain in aqueous solutionAll HCl molecules for example transfer their protons to H 2 O molecules and so the solution contains only H 3 O aq and Cl aq ions.
