4.129 Sulfites (compounds containing the SO3 2− ions) are usedas preservatives in dried fruits and vegetables and inwine making. In an experiment to test for the presenceof sulfite in fruit, a student first soaked several driedapricots in water overnight and then filtered the solutionto remove all solid particles. She then treated thesolution with hydrogen peroxide (H2O2) to oxidize thesulfite ions to sulfate ions. Finally, the sulfate ions wereprecipitated by treating the solution with a few drops ofa barium chloride (BaCl2) solution. Write a balancedequation for each of the preceding steps.
