Suspension
In chemistry, the suspension is a heterogeneous liquid containing sufficient solid particles to form the settling. Often it must be bigger than 1 micrometer. The internal phase is dispersed through the external phase through mechanical agitation with the use of certain excipients or suspension agents. Unlike colloids, the suspension will eventually abate. An example of suspension is sand in water. The suspension particles are visible under the microscope and will slow down over time if left alone. This distinguishes the suspension from the colloid ie the colloidal particles are small and not subside. Colloids and suspensions are different from solvents, ie dissolved solids do not exist in solid form, and solvents and solutes are mixed homogeneous.
