Which term reduces cohesion between particles and disperses particles of a solid in a liquid?

• A. Detergents
• B. Dispersing agents
• C. Wetting agents
• D. A sticker

Answer: (B)

Dispersing agents are substances that reduce cohesion between particles and help spread solid particles throughout a liquid, creating a stable suspension. They work by adsorbing onto particle surfaces and building an electrostatic or steric barrier that keeps particles from clumping again, so the solid stays evenly distributed in the liquid. Detergents mainly lower surface tension to aid cleaning rather than maintain dispersion, wetting agents improve how well the liquid spreads on surfaces, and “a sticker” isn’t a standard term for this function.
