A) To 0.5 mL of 3% (or 6% whichever is available in the lab) hydrogen per- oxide, H₂O₂, solution add five drops of 3 mol L-¹ sulfuric acid to acidify, then add five drops of 0.02 mol L-1 potassium permanganate solution. Gently shake the test tube. B) Dissolve a spatula-tip of sodium sulfite, Na₂SO3, in 1 mL of distilled water. To this solution add five drops of 0.02 mol L-¹ potassium permanganate solution. Gently shake the test tube. C) Dissolve as much as you can of a spatula-tip of sodium sulfite, Na₂SO3, in 20 drops of 10 mol L-¹ sodium hydroxide solution. Stir thoroughly. Add five drops of 0.02 mol L-¹ potassium permanganate solution. Gently shake the test tube. Observe the color changes in this test tube.

For each reaction (test tube A,B, and C) write balanced half-reactions and a total reaction in ionic format. Ran h reaction should have produced a reduced Mn containing product.
Transcribed Image Text:A) To 0.5 mL of 3% (or 6% whichever is available in the lab) hydrogen per-
oxide, H₂O₂, solution add five drops of 3 mol L-¹ sulfuric acid to acidify,
then add five drops of 0.02 mol L-1 potassium permanganate solution.
Gently shake the test tube.
