Detailed explanation-1: -Because of its polarity and ability to form hydrogen bonds, water makes an excellent solvent, meaning that it can dissolve many different kinds of molecules.

Detailed explanation-2: -Water’s polarity allows it to dissolve other polar substances very easily. When a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa.

Detailed explanation-3: -The property by which substances dissolve in water is called solubility. Soluble substances dissolve in water.

Detailed explanation-4: -The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding. Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).

Detailed explanation-5: -Water, which not only dissolves many compounds but also dissolves more substances than any other liquid, is considered the universal solvent. A polar molecule with partially-positive and negative charges, it readily dissolves ions and polar molecules.
