Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water is often called the “universal solvent” because many substances can be dissolved in water. What property of water allows it to be such a versatile solvent?
A
purity
B
polarity
C
high heat capacity
D
expansion upon freezing
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: -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. Each water (H2O) molecule has a little positive electric charge on the hydrogen side, whereas the oxygen side has a slight negative electric charge.

Detailed explanation-3: -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-4: -Water is a good solvent due to its polarity. The relatively small size of water molecules typically allows many water molecules to surround one molecule of solute. The partially negative dipoles of the water are attracted to positively charged components of the solute, and vice versa for the positive dipoles.
