WebA charged or polar substance that interacts with and dissolves in water is said to be hydrophilic: hydro means "water," and philic means "loving." In contrast, nonpolar molecules like oils and fats do not interact well with water. WebIons can be generally divided into two categories: cations (positively charged ions) and anions (negatively charged ions). Cations are typically hydrophobic, while anions are typically hydrophilic. This is because cations tend to have a stronger electrostatic repulsion between them, which makes them less likely to interact with water molecules.

WebHydrophilic is the physical property of a molecule that has a tendency to interact with or be dissolved by water (or other polar substances). These molecules are capable of hydrogen bonding and are typically charge-polarized . Polar and non-polar molecules are known to be hydrophilic and hydrophobic, respectively.
