Which statement about Wettable Powders is true?

Which statement about Wettable Powders is true?

• A. They are dry, finely ground solids that do not dissolve in water
• B. They readily dissolve in water to form a clear solution
• C. They form a milky emulsion when mixed with water
• D. They cannot be diluted with water

Answer: (B)

Wettable powders are dry, finely ground solids that are designed to disperse in water to form a suspension, not a true solution. When mixed with water, the powder breaks into tiny particles that remain suspended, giving a cloudy or milky appearance rather than a clear solution. This is different from soluble formulations, which actually dissolve in water to create a clear solution. Emulsifiable concentrates behave differently by forming an emulsion with oil droplets in water, not a particulate suspension. Wettable powders can be diluted to the desired concentration, but they need to be agitated to keep the suspension uniform. So the key idea is that wettable powders disperse as a suspension rather than dissolve to form a clear liquid.
