Question

redox stoichiometry

Answer 1

so I have a question regarding listing all the reactants and using them to get a balanced redox eqn

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

so I don't need the answer for this question but the answer regarding the redox eqn.

so I think its



since it said sulfite ions oxidized to sulphate, sulphate must not be a reactant right?
