Why do we add chloroform-methanol solution (7+3, v/v) to oil when determining the peroxide value of food lipid? we used IDF method and used spectrophotometric method to get the absorbance.
Homework Answers
Answer-
For the determining the peroxide value of food lipid, the IDF method is used and the spectrophotometric method is used to get the absorbance. In this method, chloroform-methanol solution (7:3, v/v) is added to the oil which acts as reaction medium for the reaction and to dissolve the sample and to verify the oxidation of Fe(II). The complexes of the ferric ion are more stable in this medium.

I need to: DETERMINE THE CONCENTRATION OF HYDROGEN PEROXIDE IN THE SOLUTION how ?? THEORY Titrimetry, or titrimetric analysis, is an example of a so-called classical method of analysis. Titrimetry is a convenient method of getting very small amounts of chemicals in to a reaction because the method involves the use of dilute solutions of reactants. Hydrogen peroxide reacts with potassium iodide according to the reaction given below: HB2BOB2B + 2HP+P + 2IP-P = IB2B + 2HB2BO (equation...
