PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following properties of water is due primarily to the polarity of the water molecule?
A
its lack of color
B
its lack of taste
C
its ability to dissolve substances
D
its ability to produce buoyant forces
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: -The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding. Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).

Detailed explanation-3: -As a result of water’s polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids.

Detailed explanation-4: -Answer and Explanation: Water is polar because it has two unshared pairs of electrons on the central oxygen molecule.

Detailed explanation-5: -Water molecules have a polar arrangement of oxygen and hydrogen atoms-one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge. This allows the water molecule to become attracted to many other different types of molecules.
