Write the formula and charge of the + ion then the
formula of the - ion. Add ions so the charges add to
zero.
Write the formula using subscripts to show how many
of each ion is needed to have a total zero charge.
Use parenthesis if more than one polyatomic ion is used.
Use ion chart for polyatomic ion formulas.

Know these four acids
Hydrochloric acid HCl
Bases have
Acetic acid HC2H3O2
OH1-
Carbonic Acid H2CO3
Ex: NaOH
Sulfuric acid H2SO4
Use the polyatomic ion chart to help you: Carbonate
is CO32-. All acids have H+ and we need 2 H+ to
balance the charges!
