Q. Water can dissolve more substances than any other liquid because

[A] It is dipolar in nature

[B] It is a good conductor of heat

[C] It has high value of specific heat

[D] It is an oxide of hydrogen

Answer: A

Why this Question) Important static science concept. 

Ans) a 

Exp) Option a is correct. 

Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients. 

It is water’s chemical composition and physical attributes that make it such an excellent solvent. Water molecules have a polar arrangement of oxygen and hydrogen atomsone 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.  

Water can become so heavily attracted to a different compound, like salt (NaCl), that it can disrupt the attractive forces that hold the sodium and chloride in the salt compound together and, thus, dissolve it.
