I am a student of grade 12. For my chemistry investigatory project I was planning to do unsaturation of oils. The aim of the experiment is to find the relative unsaturation in 3 different samples of vegetable oil by halogen titration (titrating it against standardized iodine solution). It requires us to dissolve the oil sample (.15g) in 20 ml chloroform. But in our school we are not allowed to use chloroform. So can anyone suggest me another substitute for chloroform (which is less hazardous) in this experiment. Please help me - it is urgent. Thanx in advance for any help.
I had posted this earlier before reading the rules. So I am posting it again with the proper subject.

I don't see why methylene chloride wouldn't work instead of chloroform.

Hi,

I have never come across methylene chloride. Could you give the formula of this substance?


Thanks

Methylene chloride is one of those chemicals that's called different things depending on where you live: dichloromethane, DCM, or CH2Cl2, it's formula
