Question

Is milk a solution, colloid or a suspension? is it homogeneous or heterogeneous? how can it's component be separated?​

Answer 1

Answer:

Due to the relatively smaller size of particles, as compared to that of a suspension, the mixture appears to be homogeneous. But actually, a colloidal solution is a heterogeneous mixture, for example, milk. Because of the small size of colloidal particles, we cannot see them with eyes.
