what is the name of the $\text{so}_3^{2-}$ ion?

sulfite

hypersulfate

sulfate

sulfur

Explanation:

First Question (NO₃⁻ ion):

Nitrate ion has the formula \( \text{NO}_3^- \). Nitrite is \( \text{NO}_2^- \), nitrous is related to \( \text{HNO}_2 \), and nitrogen is the element \( \text{N} \). So the correct name for \( \text{NO}_3^- \) is Nitrate.

Sulfite ion has the formula \( \text{SO}_3^{2-} \). Sulfate is \( \text{SO}_4^{2-} \), hypersulfate is not a standard ion name here, and sulfur is the element \( \text{S} \). So the correct name for \( \text{SO}_3^{2-} \) is Sulfite.

Answer:

C. Nitrate

Second Question (SO₃²⁻ ion):
