Fill in your table of polyatomic ions using the

mnemonic

Now you can create salts with these polyatomic

ions

magnesium & carbonate

magnesium & carbonate

Mg2+ & CO32-

magnesium & carbonate

Mg2+ & CO32-

= MgCO3

magnesium & carbonate

Mg2+ & CO32-

= MgCO3

magnesium carbonate

sodium & phosphate

sodium & phosphate

Na+ and PO43-

sodium & phosphate

Na+ and PO43-

= Na3PO4

sodium & phosphate

Na+ and PO43-

= Na3PO4sodium phosphate

sodium & phosphate

Na+ and PO43-

= Na3PO4sodium phosphate

aluminum & sulfate

Al3+ and SO42-

= Al2(SO4)3aluminum sulfate

See how many salts you can create!
