Question

the picture below shows a mixture that was stirred 3 minutes ago. what should this mixture be classified as? colloid

Explanation:

Colloids do not separate upon standing for a short - time. Since the mixture in the beaker has separated into two distinct layers 3 minutes after stirring, it is not a colloid. It is more likely a suspension as suspensions are heterogeneous mixtures where the particles settle out over time.

Answer:

Not a colloid (it is likely a suspension)
