(4b-102) Only using the list of ions below, form two ionic compounds that would be soluble in water, and two ionic compounds that would be insoluble in water. You should make four different compounds, but you may use ions more than once. Be sure to indicate which is which, and make sure your compounds are charge-balanced!
