Which type of mixture can be separated by filtration?

The correct response is based on the characteristics of a suspension. A suspension is a heterogeneous mixture in which solid particles are dispersed throughout a liquid or gas but are not dissolved. These particles are large enough to be separated from the liquid by physical means, such as filtration. When a suspension is passed through a filter, the larger solid particles will be trapped by the filter paper, allowing the liquid to pass through. This property allows for the effective separation of the components in a suspension.

In contrast, a solution is a homogeneous mixture where the solute is fully dissolved in the solvent, making it impossible to separate the components by filtration. Meanwhile, an emulsion, which is a mixture of two immiscible liquids (like oil and water), does not settle into layers easily and typically requires different methods for separation, such as centrifugation or the addition of emulsifying agents. A mixture is a general term that encompasses both homogeneous and heterogeneous mixtures, so it does not specifically pertain to the ability to be separated by filtration.
