What are the unique properties of water? Why are they important?

Interpretation Introduction

Interpretation:

The unique properties of water are to be provided and their importance is to be determined.

Concept Introduction:

Water is a common liquid that is present on the Earth.

It is also known as universal solvent. It can dissolve a wide range of organic and inorganic solutes.

Water is vital for the existence of all living animals. Without water, no life form can exist, it constitutes an important part of rivers, lakes, streams, clouds, snow and ice.

Water is truly an unusual molecule such that being a low molar mass compound, it exists as a liquid at room temperature and has an anonymously high boiling point.

Ice floats on water because it has a lower density than water.

The temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere is called boiling point.

A hydrogen bonding is a partially electrostatic force of attraction between a hydrogen atom which is bound to more electronegative atom such as nitrogen, oxygen or fluorine and another atom bearing a lone pair of electrons.

A molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule

Explanation of Solution

Water is a vital molecule for living organisms which exists as a liquid at room temperature with quite a low molar mass. It contains two hydrogen atoms bonded with a single oxygen atom. Due to the presence of oxygen atoms, water becomes a polar molecule. Also, oxygen of one water molecule bonds with the hydrogen atom of another molecule which leads to intermolecular hydrogen bonding. This is the reason why oxygen has a high boiling point with a low molecular mass. Also, water is a polar molecule but can dissolve a wide range of organic and inorganic solutes. It leads to the proper functioning of biological systems and survival of living organisms...
