with others? Oil and water don't mix Gasoline and water also do not mix. However, gasoline and oil do mix. To understand solubility we must look at two important characteristics: geometry and bond polarity (ionic. nonpolar and polar). From these two characteristics the overall molecular polarity can be determined. The statement "like dissolves like" provides a good basis for understanding solubility. A substance with similar characteristics will mix with another substance with similar characteristics. This can be summarized as polar...
