Chemical Properties of Water as a Universal Solvent

S&TMaterials & NanotechnologyFactual singleEasyStatic

Question

Water can dissolve more substances than any other liquid because

Options

a

it is dipolar in nature

Answer
b

it is a good conductor of heat

c

it has high value of specific heat

d

it is an oxide of hydrogen

Explanation

Water features a highly asymmetrical arrangement of hydrogen and oxygen atoms, which creates a strong dipole moment with positive and negative poles. This dipolar nature allows water molecules to break the electrostatic bonds of ionic solutes and surround them via hydration spheres, making it an incredibly effective universal solvent. > The strong dipolar structure of water molecules allows it to dissolve a wide range of polar and ionic solutes. Answer: (a).
