Suspension and Aqueous Suspension

A suspension is a type of mixture where solids are dispersed in a liquid in such a way that the solid particles do not dissolve. Instead, they are suspended in the liquid, giving the mixture a cloudy appearance. The solid particles may settle over time, requiring the mixture to be stirred to re-disperse the solids. Examples of suspensions include mud, blood, paint, and many food products like milk or orange juice.

An aqueous suspension is a type of suspension in which the solid particles are suspended in a water-based liquid. The solid particles are usually larger than one micrometer and are dispersed throughout the liquid, making the mixture heterogeneous. The particles may settle over time due to gravity, but can be kept suspended by constant agitation. Aqueous suspensions are commonly used in pharmaceuticals, cosmetics, and certain food products.

Note that an aqueous suspension is a type of suspension. A suspension is a heterogeneous mixture of a solid and a liquid in which the solid is dispersed in the liquid, while an aqueous suspension is a type of suspension in which the liquid component is water. The main difference between the two is the type of liquid component used in the mixture.
