Expert Solution

Lipid solubility is to the ability for a molecule to dissolve in lipids, which is dependent on its polarity. Non-polar molecules to be lipid soluble.

The lipid solubility is also known as lipophilicity, it is usually refers to the capability of a substance or compound to dissolve in lipids, fats, or oils, lipids.

The substances which are soluble or dissolve in lipids are soluble in non-polar solvents such as hexane or toluene. The substances or chemicals which have the ability to dissolve in fat or non-polar solvents are known as lipophilic substances. However, these substances are unable to dissolve in polar or hydrophilic (water-loving) substances.

All drugs that pass the blood-brain barrier are at least lipid-soluble.

Water solubility is a measure of the amount of chemical substance that can dissolve in water at a specific temperature. The unit of solubility is generally in mg/L (milligrams per liter) or ppm (parts per million).

Sugar and salt, some pesticides are very soluble in water. They dissolve easily. Their molecules bond to water molecules. Highly soluble pesticides will travel with water as it moves in the environment.

The solubility of water in water is 100% of the water soluble, if the solvent is olive oil (nonpolar solvent) then the solubility of water decreases dramatically.
