Homogeneous mixture

Homo = same

In a homogeneous mixture, we cannot differentiate its components easily, the appearance and composition is uniform

Example = Salt solution, we cannot easily differentiate salt and water in the same way sugar solution and even vodka is also a homogeneous mixture since it is product of neutral distillation of sprit that is ethanol plus water.

Heterogeneous mixture

Hetero = different

In heterogeneous mixture we can distinguish different components, easy to differentiate.

Example = sand and water, sand is not miscible in  water thus easily distinguishable, and mixture of water and petrol is also a heterogeneous mixture where the components are easily visible.
