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: -Water is a Polar Covalent Molecule The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Detailed explanation-4: -Polar molecules attract water molecules, mainly through hydrogen bonding. They compete successfully with hydrogen bonds between the water molecules, so they are readily soluble in water.
Detailed explanation-5: -Because water is polar, with slight positive and negative charges, ionic compounds and polar molecules can readily dissolve in it. Water is, therefore, what is referred to as a solvent-a substance capable of dissolving another substance.
