Dissolving of Ionic Compounds Ionic compounds break apart (dissociate) into their ions when placed in water Called aqueous solutions (aq)

Aluminum bromide Iron (III) hydroxide Barium perchlorate Ammonium dichromate

Stoichiometry and ionic solutions 1. magnesium fluoride If one mole of this dissolves, how many moles of fluorine ion are in solution? 2. copper (II) phosphate If 9.0 moles dissolve, how many total moles of ions are present?

3. Calcium acetate If 45.6g of calcium acetate dissolve, how many total moles of ions are in solution?
