For each of the following compounds decide what the charge of the anion and the cation is respectively. If the cation or anion is a polyatomic ion, you may simple state the charge on the entire polyatomic ion. (For example if PO. is present it would simple be-3). 5. a. CaO Anion: Cation: b. Fe2O Anion:_ Cation: c. Ba(OH);2 Anion: cation: d. NaOH Anion: Cation: e. NH4CI Anion: Cation: f. Na2COs Anion: Cation: g. K2SO4 Anion: Cation:_
