Give a test that can be used to differentiate chemically between butter and cooking oil.
Answer:
- Butter is a saturated compound whereas cooking oil is unsaturated.
- Hence, if we add alkaline potassium permanganate (alk KMnO 4 ) which is pink in color to the cooking oil, it will decolorize potassium permanganate.
- However, this will not happen in the case of butter because it is saturated.
