Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What property of water makes it the ‘universal solvent’?
A
it is a polar molecule
B
it is an ionic compound
C
it contains hydrogen bonds
D
it steals electrons from other atoms
Explanation: 

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: -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. Because of the polarity of each water molecule, water is a solvent.

Detailed explanation-3: -Unique properties of water Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons. Water is an excellent solvent.

Detailed explanation-4: -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.
