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 extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent, ” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients.

Detailed explanation-3: -Water is often called the “universal solvent” because many substances can be dissolved in water.

Detailed explanation-4: -Water is called a ‘universal solvent’ because water can dissolve much more substances than any other liquid found in nature but water cannot dissolve every substance. For example-water cannot dissolve fats, waxes, and hydroxides due to the low solubility of oppositely charged particles.

Detailed explanation-5: -Water has cohesive and adhesive properties. Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid’s surface to resist rupture when placed under tension or stress.
