In this experiment, I am to determine the amount of CaO in
limeston. BUT I don't understnad why I am doing this
procedures.
1. preparation of 0.02M potassium permanganate (to use as
titrant)
2.standardization of potassium permanganate solutions
(WHY?)
3. titrate sodium oxoalate with KMnO4 permanganate (WHY?)
determination of calcium in a limestone
4. sample preparation
5. precipitation of calcium oxalate (WHY?)
6. titrate calcium oxalate with KMnO4 permanganate (WHY?)
