Rules to help remember ions:

Per- prefix has 1 more O than -ate Ex:  Perchlorate = ClO₄^-

-ate ending has 1 more O than -ite Ex:  Chlorate = ClO₃^-

-ite ending has 1 less O than -ate Ex:  Chlorite = ClO₂^- 

Hypo- prefix has 1 less O than -ite Ex:  Hypochlorite = ClO^-

Bi- prefix has an H⁺ on ion Ex:  Bicarbonate = HCO₃^-
