Which formulation requires constant agitation to maintain dispersion in tank?

Which formulation requires constant agitation to maintain dispersion in tank?

• A. Liquid suspension
• B. Water soluble concentrate
• C. Wettable powder
• D. Granules

Answer: (A)

A liquid suspension consists of fine solid particles dispersed in a liquid, and those particles tend to settle out without constant stirring. To keep the solid particles evenly distributed in the tank and ensure a uniform application, you need continuous agitation. Water soluble concentrates dissolve completely in water, so once fully mixed there aren’t suspended solids to settle. Wettable powders are solid particles that must be wetted and dispersed; they can settle if agitation stops, but they aren’t in a true suspended state like a liquid suspension. Granules are larger solid carriers that dissolve or disperse differently and generally don’t require continuous agitation to stay dispersed in the same way.
