**Problem Statement:** What is the molarity of a sodium vanadate (\(\text{Na}_3\text{VO}_4\)) solution if 35.6 mL of the solution are needed to titrate a 0.499 g sample of pure potassium sulfite? **Chemical Reaction:** \[ \text{VO}_4^{3-} + \text{SO}_3^{2-} + 4\text{H}^+ \rightarrow \text{VO}^{2+} + \text{SO}_4^{2-} + \text{H}_2\text{O} \] **Explanation:** This problem involves calculating the molarity of a sodium vanadate solution based on its use in titrating potassium sulfite. The chemical equation shows the reaction between vanadate ions, sulfite ions, and hydrogen ions, resulting in vanadium(II) ions, sulfate ions, and water. The procedure typically involves stoichiometry and molarity concepts to find the concentration of the sodium vanadate in the original solution.
