Usually for other compounds mostly we use water for dilution. Do the same with rancid vegetable oil. Acetone acts as a good solvent for many organic chemicals because it contains nonpolar C–C and C–H bonds as well as a highly polar C=O. As you can see, Peeps seem about as happy in acetone as they are in water. Substances may combine together poorly or very well, and it's possible to describe solutions as "partially soluble" or "mostly soluble." Solubility of vegetable oil in different solvents: A.
