Detailed explanation-1: -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.
Detailed explanation-2: -Water is a polar molecule due to the unequal distribution of its electron density. Because there is a difference in electronegativity between hydrogen and oxygen, this shows that water is a polar molecule. Water is known as the universal solvent because it can dissolve more compounds than any other liquid.
Detailed explanation-3: -The polarity of water molecules allows liquid water to act as a “universal solvent, ‘’ able to dissolve many ionic and polar covalent compounds. The polarity of water molecules also results in strong hydrogen bonds that give rise to phenomena such as surface tension, adhesion, and cohesion.
Detailed explanation-4: -Water molecules attract each other due to polarity. Polarity: Although the net charge of a water molecule is zero, water is polar because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules.
