Question

If you were to draw diagrams representing aqueous solutions of each of the following ionic compounds, how many anions would you show if each diagram contained six cations? Enter your answers as numbers, not words, in the spaces below.

K₃PO₄ _

Ca(NO₃)₂ _

MgSO₄ _

Answer 1

K₃PO₄ 2 because there is 1 anion (PO₄^3-) for 3 cations (K⁺)

Ca(NO₃)₂ 12 because there are 2 anions (NO₃^-) for each cation (Ca²⁺)

MgSO₄ 6 because there is 1 anion (SO₄^2-) for each cation (Mg²⁺)
