What is the process used to separate colloidal solutes from crystalloid solutes?

• A. Filtration
• B. Dialysis
• C. Distillation
• D. Centrifugation

Answer: (B)

Dialysis uses a semipermeable membrane that lets small dissolved particles (crystalloids) diffuse through while larger colloidal particles are retained. This size-based separation is exactly what distinguishes colloidal solutes from crystalloid solutes, making dialysis the appropriate method. Filtration relies on a barrier and pressure but isn’t as selective for separating colloids from crystalloids in solution. Distillation depends on boiling points and isn’t applicable to dissolved solutes in a liquid. Centrifugation separates mainly by density and doesn’t provide the targeted size-based separation across a membrane.
