Question | Answer |
Acetate | (C2H3O2)-1 |
Carbonate | (CO3)-2 |
Nitrite | (NO2)-1 |
Nitrate | (NO3)-1 |
Sulfite | (SO3)-2 |
Sulfate | (SO4)-2 |
Phosphate | (PO4)-3 |
Chromate | (CrO4)-2 |
Dichromate | (Cr2O7)-2 |
Permanganate | (MnO4)-1 |
Hydroxide | (OH)-1 |
Cyanide | (CN)-1 |
Bicarbonate | (HCO3)-1 |
Bisulfite | (HSO3)-1 |
Bisulfate | (HSO4)-1 |
What happens when you add a Hydrogen to a Polyatomic Ion? | You add a Bi- prefix to the Ionic name and adjust the charge to include the H+1. Example: Sulfate(-2) becomes Bisulfate(-1). |
Ammonium | (NH4)+1 |
Hydronium | (H3O)+1 |
Are Cations positive or negative? | They are positive. An easy way to remember is to use the "t" in Cat: Cat ions Ca+ ions |
Are Anions positive or negative? | They are negative. An easy way to remember is the "n" in An aN ion a(-) ion |
Name two (+1) Polyatomic Cations. | Ammonium & Hydronium |
Name six (-1) Polyatomic Anions. (do not include any of the Bi- hydrogens) | Acetate, Nitrate, Nitrite, Permanganate, Hydroxide, Cyanide |
Name five (-2) Polyatomic Anions. (do not include any of the Bi- Hydrogens) | Carbonate, Sulfate, Sulfite, Chromate, Dichromate |
Name one (-3) Polyatomic Anion. | Phosphate |
Adding or subtracting Oxygen to a Polyatomic Anion changes: 1. Its name 2. Its charge 3. Both its name and charge 4. Neither its name or charge | Changes: 1. Its name Ex: Sulfite (SO3)-2 Sulfate (SO4)-2 Nitrite (NO2)-1 Nitrate (NO3)-1 |
Adding or subtracting Hydrogen to a Polyatomic Anion changes: 1. Its name 2. Its charge 3. Both its name and charge 4. Neither its name or charge | Changes: 3. Both its name and charge Ex: Carbonate (CO3)-2 Bicarbonate (HCO3)-1 |
