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!
