Polyatomic Ions Ch.2

Focusing on 14 common Polyatomic Ions (The S.A. CHEM 1000-1025 List )

QuestionAnswer
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
