Question

what is the name of this ionic compound? na₂so₃ sodium sulfur oxide sodium sulfite sodium sulfide sodium sulfate

Explanation:

To name the ionic compound \( \text{Na}_2\text{SO}_3 \), we first identify the ions. Sodium (\( \text{Na}^+ \)) is the cation. The anion is \( \text{SO}_3^{2-} \), which is the sulfite ion (sulfate is \( \text{SO}_4^{2-} \), sulfide is \( \text{S}^{2-} \), and "sulfur oxide" is not a standard ion name). So combining sodium and sulfite gives sodium sulfite.

Answer:

B. Sodium sulfite
