Question

what is the name of this ionic compound? k₂co₃ dipotassium carbontrioxide krypton carbonate potassium chlorate potassium carbonate

Explanation:

• For ionic compounds, the name is formed by stating the cation (positive ion) first and then the anion (negative ion).
• Here, the cation is \(K^{+}\) (potassium ion) and the anion is \(CO_{3}^{2 -}\) (carbonate ion).
• "Dipotassium carbontrioxide" is an incorrect naming as the standard naming for ionic compounds doesn't use such prefixes in this way for simple ionic compounds like \(K_{2}CO_{3}\).
• "Krypton carbonate" is wrong because the cation is potassium (\(K\)) not krypton (\(Kr\)).
• "Potassium chlorate" would be for \(KClO_{3}\) (where the anion is \(ClO_{3}^{-}\), chlorate ion), not for \(K_{2}CO_{3}\).

Answer:

potassium carbonate
