Which process describes the dispersion of solid particles in a liquid pesticide?

The process that describes the dispersion of solid particles in a liquid pesticide is referred to as a suspension. In a suspension, solid particles are dispersed throughout a liquid but do not dissolve, meaning they can eventually settle at the bottom if left undisturbed. This characteristic is important in the formulation of pesticides, as these particles can contain active ingredients that need to be applied effectively to control pests.

In contrast, an emulsion involves mixing two immiscible liquids, where one liquid is dispersed in the other, and a solution refers to a mixture where one substance is completely dissolved within another, creating a homogeneous blend. Concentration is a term used to describe the amount of a substance in a given volume of solution, rather than a method of dispersion. Understanding these distinctions is critical for pesticide applicators as they determine the appropriate methods for application and the effectiveness of the pesticide formulation.
