Question

IS MILK A HOMOGENEOUS MIXTURE OR HETEROGENEOUS MIXTURE ?

Answer 1

Its neither Homogeneous mixture or Heterogeneous mixture. It's Colloidal Solution, the particles of the milk are pretty stable and thus colloidal. They never settle down and give tyndall effect when light is passed through it.

Answer 2

Milk is a colloidal solution.

The colloidal solution is a mixture that is actually heterogeneous mixture but appears to be a homogeneous mixture as the particles are uniformly spread throughout the solution.

Heterogeneous mixture -

The mixture which does not have the same composition throughout. The components are distributed uniformly. The components can be distinguished from each other.

Examples - Sand in water, iron nails in the sand, pebbles in rice.

Homogeneous mixture -

The mixture that has the same composition throughout. The components are distributed uniformly. The components can be distinguished from each other.

Examples - Salt in water, sugar in water.
