. An acid is a substance that dissolves in water to form H+/H3O+ as the only positive ion/cation. This is called the Arrhenius definition of an acid. From this definition, an acid dissociate/ionize in water releasing H+ thus:

HCl(aq) -> H+ (aq) + Cl- (aq)
HNO3(aq) -> H+ (aq) + NO3- (aq)
CH3COOH(aq) -> H+ (aq) + CH3COO-(aq)
H2SO4(aq) -> 2H+ (aq) + SO42-(aq)
H2CO3(aq) -> 2H+ (aq) + CO32-(aq)
H3PO4(aq) -> 3H+ (aq) + PO43-(aq)
