Relating Relative Numbers of Anions and Cations to Chemical Formulas
The accompanying diagram represents an aqueous solution of either MgCI2, KCI, or K2SO4. Which solution does the drawing best represent?
If you were to draw diagrams representing aqueous solutions of (a) NiSO4, (b) Ca(NO3)2, (c) Na3PO4, (d) AI2(SO4)3, how many anions would you show if each diagram contained six cations?
