Experiment #1 Take 3 test tubes & 3-4 drops of the Potassium permanganate solution.
Add to the 3 test tubes.
In the 1st test tube, add 3-4 drops of concentrated Nitric acid.
In the 2nd test tube, add the same drops of Sodium hydroxide.
And, to the 3rd one add the same drops of water.
Then, add a little bit of crystalline Sodium sulfite in all 3 test tubes & steer until complete dissolution of
the crystals. As you noted, magnesium in a compound at different oxidation states. Has different
characteristic colors. Describe the colors & write redox reaction equations of into reactions of sodium
sulfite & Potassium permanganate. Solution in acidic, neutral, and alkaline-medium.​
