Which term describes mixtures formed by dissolving a substance in a liquid that do not settle out and do not require agitation?

• A. Solutions
• B. Suspensions
• C. Emulsions
• D. Fumigants

Answer: (A)

Mixing that forms a true solution results in a uniform, one-phase mixture where the dissolved substance becomes part of the liquid at the molecular or ionic level. Because the particles are so small, they don’t settle out over time, and the mixture stays evenly distributed without constant stirring. This is different from suspensions, where larger particles float or sink and will separate unless you continuously mix; and from emulsions, where one liquid is dispersed as droplets within another and can also separate over time. In pesticide terms, a solution is a liquid where the pesticide is dissolved completely in a solvent, giving a stable, homogeneous product that doesn’t require agitation to stay mixed.
