Question

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

Explanation:

• For ionic compounds, the naming rule is: name the cation first, then the anion.
• In \(K_2CO_3\), the cation is \(K^{+}\) (potassium ion) and the anion is \(CO_3^{2 -}\) (carbonate ion).
• "Potassium chlorate" has the anion \(ClO_3^{-}\), so it is incorrect.
• "Dipotassium carbontrioxide" is not the standard naming for \(K_2CO_3\).
• "Krypton carbonate": Krypton (\(Kr\)) is a noble gas and not involved in forming this compound as \(K_2CO_3\) contains potassium (\(K\)) not krypton.

Answer:

potassium carbonate
