The polyatomic Ions There are 3 with a -2 charge SO42– …..Sulfate SO32– …...Sulfite CO32– ……Carbonate
SO42– Sulfate
SO32– Sulfite
CO32– Carbonate
There is only 1 with a +1 charge NH41+……. Ammonium
NH41+ Ammonium
There are several with a -1 charge ClO41–…perchlorate ClO31–…chlorate ClO21–…chlorite ClO1–…hypochlorite Do you see a pattern?
One of these is nitrite the other is nitrate NO31–………………. NO21–……………….
More -1 charges HCO31–…Bicarbonate HSO41–…Bisulfate HSO31–…Bisulfite Do you see a pattern?
More -1 ions OH1–……..…Hydroxide CH3COO1–………….acetate (also C2H3O2-1) MnO41–……….permanganate
And there is only one -3 ion PO43–……………….phosphate
