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 molecules have a polar arrangement of oxygen and hydrogen atoms-one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge. This allows the water molecule to become attracted to many other different types of molecules.

Detailed explanation-3: -Because of their polarity, water molecules are strongly attracted to one another, which gives water a high surface tension. The molecules at the surface of the water “stick together” to form a type of ‘skin’ on the water, strong enough to support very light objects.

Detailed explanation-4: -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.

Detailed explanation-5: -The high dielectric constant and dipole movement of water are the properties of water that make it useful as a solvent. Water can dissolve ionic compounds and hydrolyze them. Note: Though water is a polar solvent and polar solvents are able to dissolve only polar compounds in them.
