Solubility test for lipids observation
Weba) Solubility Test: Fats are soluble in organic solvents like chloroform, alcohol, etc. It is insoluble in water. So, if the given sample forms an oily layer above the surface of the … WebThe experiment gives a rough comparison of the degrees of unsaturation of the oils and fats tested, but the results cannot be translated into a quantitative comparison. If students find the colour change to a permanent yellow difficult to distinguish, a variation can be tried using potassium manganate(VII) solution, KMnO 4 (aq), 0.0005 M instead.
