Petrol as a solvent
Petrol as a solvent

Description

The students will learn that fatty components of foods such as peanuts, margarine and cooking oil can be dissolved with petroleum ether with high boiling point. Because petrol, being a non-polar solvent, has a high lipophilic content, the phenomenon is based on the principle “like dissolves in like”.
