Question

Is milk a homogenous mixture or a heterogeneous mixture?

Answer 1

Under a microscope, milk can be considered heterogeneous because the lipid (fat) cells that give milk its white appearance are not actually dissolved into the water that makes up the rest of the substance. ... In addition to being a homogeneous mixture, milk is also a colloid.

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.
