Final answer:
Common anions include acetate (CH3COO-), manganate (MnO4²-), nitrate (NO3-), and carbonate (CO3²-). The naming of ionic compounds involves stating the cation first and then the anion, ensuring that the charges balance.
Step-by-step explanation:
The question pertains to the identification and naming of anions which are negatively charged ions found in various ionic compounds. Anions are typically formed when an atom gains electrons, resulting in a net negative charge. Here are the names and formulas of some common anions:
- Acetate (ethanoate) - CH3COO-
- Manganate - MnO4²-
- Nitrate - NO3-
- Carbonate - CO3²-
- Nitrite - NO2-
- Hypochlorite - CIO-
- Oxalate - C2O4²-
- Chromate - CrO4²-
- Oxide - O2-
- Cyanide - CN-
When naming ionic compounds, the name of the cation (the positively charged ion) is stated first, followed by the anion. Ionic compounds must have a balance of positive and negative charges, so the charges on the cations and anions must be equal when combined.
