Question

Maria examines a mixture that appears to be the same throughout. However, when she looks at a sample using a magnifying lens, she can see small droplets of liquid surrounded by another liquid.

Which conclusion best fits her observations?

The mixture is a solution because it has the same appearance throughout the sample.
The mixture is a suspension because it is composed of two different-appearing substances.
The mixture is a homogeneous mixture because one liquid is dissolved in the other.
The mixture is a colloid because two different substances can be seen in a small sample.

Answer 1

The mixture is a colloid because it looks uniform to the naked eye but shows tiny droplets of one liquid dispersed in another when magnified (an emulsion is a liquid–liquid colloid).
