Dear user,

1)Sedimentation :When a heavier component in a mixture settles down when we add water to it is termed as sedimentation.

2)Evaporation :

It is defined as the process of conversion of water into its vapour state.

3)Condensation :

It is defined as the process by which water vapour in air gets converted into liquid waetr.

4)Dissolution :

It is basically addition of one substance to another and making a solution that is one substance gets dissolved in other.

For example :

When we add salt in water,it gets dissolved in water.

Now,all the methods basically separates one component from another component but dissolution does not separate anything,

it actually dissolves one substance to other.

Therfore,dissolution is odd one out.

Answer 2

Chlorination is the odd one it here because the rest are separating methods but chlorination is purifying method.
