Solution
A water molecules contain two oxygen atoms and one hydrogen atom. Since the oxygen atom is
partially electro-negative and hydrogen atom is partially electro-positive in nature, the water
molecules get partially charged with positive and negative charges. This distribution of charges
on water atoms formulates the basis for dissolution of various solutes and formation of hydrogen
bonds in water.
When water is added to a solution or any hydrophilic solute is added to water, the distribution of
partial charges on the water molecule disperses the solute into different ionic states and forms
hydrogen bonds with the solute. This constant formation of hydrogen bonds of water molecules
with the solute helps in dissolution of solute and maintain fluid state of water. Depending upon
the nature of solute, the dissolution can be endothermic, exothermic or athermic in nature.
However, heating of water leads to increase in randomness of water molecules thus increasing
solubility of solutes in water.
Thus, dissolution of solute and behaviour of water depends upon the nature of solute and
physical properties of water and solute along with external factors such as temperature etc.
