Aim: Determination of saponification value of given an oil sample Principle: Saponification value defines as the number of mg of KOH required to saponify or hydrolysis 1 g of oil/fat. In this estimation KOH reacts with the fat/oil to gives glycerol and the potassium salt of the corresponding fatty acid. KOH is added in excess [...]
Aim: Determination of iodine value of an oil sample Principal: Iodine value is define as the number of g. of halogen as iodine, that is absorbed by 100 g, of fat/oil. It is a measure of the degree of unsaturation of the sample. The fat oil is treated with an excess of wij’s solution (Iodine [...]
