When charged or polar molecules are dissolved in water the water molecules form

Question

When charged or polar molecules are dissolved in water the water molecules form around the molecules. Solubility of substances: Substances/molecules are either soluble in water, are partially soluble in water or insoluble in water. These different solubilities give rise to three classes of molecules which are described below: 1. Hydrophilic . Carry charges? .Dissolve in water? Can include covalently bonded molecules? Can include ionically bonded molecules? Examples: Type . 2. Carry charges? . Dissolve in water? . Tyne: non-polar

Explanation / Answer

Ans) Solubility of substances-

Hydrophilic molecules are molecules that can dissolve in water. These molecules must have a charge (positive or negative) in order to interact with water, which is polar. Meaning that the molecule has a partially positive side and a partially negative side.

1. Hydrophilic -

Ions that have a positive charge are called cations, and ions that have negative charge are called anions. But regardless of whether the charge is positive or negative, ions are hydrophilic and can interact with water.

2. Hydrophobic-

3. Amphiphillic or amphipathic -

Examples- cholesterol, lipids.

lipids, are known as amphipathic molecules. These molecules have two distinct ends to them: a water-loving (hydrophilic) side and a water-fearing (hydrophobic) side.

Ans) Acids and bases-
