Match the following polyatomic ions. Match the items in the top column to the items in the bottom column.

1. NO3-
2. (SO4)2-
3. NH4+
4. (CO3)2-
5. MnO4-
6. (PO4)3-
7. C2H3O2-
8. (CrO4)2-
9. (Cr2O7)2-
10. SO32-

-phosphate
-chromate
-ammonium
-sulfite
-dichromate
-carbonate
-nitrate
-permanganate
-sulfate
-acetate

Answer 1

1. nitrate
2.sulfate
3.ammonium
4. carbonate
5.permanganate
6. phosphate
7. acetate
8.chromate
9.dichromate
10.sulfite
done!

Answer 2

There are some rules and conventions surrounding these. For example, sulfate and sulfite, the '-ite' always will have one less oxygen than the '-ate'. Let me use chlorate here as an example to show this naming convention entirely.
Chloride Cl
Hypochlorite ClO
Chlorite ClO2
Chlorate ClO3
Perchlorate ClO4
The charge on all of these is the same (-1 in the chlorine case)
The second rule is a prefix of 'bi-' indicates that a hydrogen is added to the base ion and the charge has been increased by 1.

Of course, usual rules hold as well. So dichromate would indicate two chromium atoms in the ion. (Cr2O7)

Others you're just going to have to memorize, like ammonium (NH4), acetate(C2H3O2)
