Solution:
Ice and air is a homogeneous mixture.Homogeneous and heterogeneous are two classes in which mixtures are divided.
Homogeneous mixtures are also known as true solutions. Suspension and colloidal are examples of heterogeneous mixtures, and they can be separated by filtration. Heterogeneous mixtures show the Tyndall effect. Homogeneous mixtures of solute and solvent cannot be separated by filtration.
