Question

In a chemical analysis of a chromium alloy, all of the chromium is first converted to chromate ions. A 50.0 mL sample of the chromate ion solution is then reduced in a basic solution to chromium(III) hydroxide by reaction with 22.6 mL of 1.08 mol/L sodium sulfite. In this reaction, the sulfite ions are oxidized to sulfate ions. What is the amount concentration of the chromate ion solution?
