Final answer:
A monodispersed solution is a type of solution where the solute particles are of uniform size, whereas in a polydispersed solution, the solute particles have a wide range of sizes.
Step-by-step explanation:
A solution is a homogeneous mixture in which solute particles are dispersed uniformly throughout a solvent. A monodispersed solution is a type of solution where the solute particles are of uniform size. On the other hand, a polydispersed solution is a type of solution where the solute particles have a wide range of sizes.
For example, if we dissolve only one size of sugar particles in water, we get a monodispersed solution. But if we dissolve sugar particles of different sizes in water, we get a polydispersed solution.
In summary, monodispersed solutions have solute particles of uniform size, while polydispersed solutions have a wide range of sizes for the solute particles.
