Here is a picture of the question In part c They add drops of KMnO4 to a solution which contains Fe2+ ions and they ask about the color change
When I read the question I thought, the color change they want is the color change of the solution but turns out They want the color change of the KMnO4 ( from the MS) How can I tell ?
Because you are adding the MnO4 to the solution in the flask, which is Fe2+. At the end it will be pink (Mn2+) However, it you were to add the Fe2+ to the MnO4, the MnO4 would be purple, and at the end will be pink again (Mn2+).
