Question

Q. Why air is not a Homogeneous Mixture , As it is evenly distributed through out the Atmosphere . Where as ICE is said as Homogeneous , but ICE has molecules as well as Chemical Combination . It cant be Categorized in the Group Of Mixtures ( as a Homogeneous ) ?

Answer 1

Air in its pure form is a homogeneous mixture of gases like nitrogen, oxygen, carbon dioxide, argon and various other gases in smaller amounts. However it becomes heterogeneous when it is polluted and additional harmful elements are added to it.




Ice in Water. When you add ice, or frozen water, to pure water, you have created a heterogeneous mixture of a pure substance. The atoms in the ice are locked in a crystalline matrix whose atoms are less densely packed than those in the liquid water, a unique property of water.
