HELP Place about 3 mL of 0.01 M acidified iron (II) sulfate, FeSO4, in a test tube.
Using a clean eyedropper, add 6 drops of 0.01 M potassium permanganate, KMnO4, 1 drop at a time, shaking the test tube after each additional drop.
What do the reactants look like?
What happens when the reactants are combined? Make observations concerning anything that might indicate a chemical reaction, such as production of a gas or a precipitate, color change or temperature change (did the test tube get cold or hot?).
Why do you think a reaction has, or has not, occurred?
