To separate very small insoluble particles from a liquid, techniques that enhance sedimentation or filtration are required. Centrifugation (C) is a process that uses centrifugal force to accelerate the sedimentation of particles suspended in a liquid. This is particularly effective for separating very fine or colloidal particles that would settle very slowly or not at all under gravity alone. Crystallization (A) is for dissolved substances. Fractional distillation (B) is for separating miscible liquids with different boiling points. Decantation (D) involves carefully pouring off the liquid after the solid has settled, which is less effective for very small particles that remain suspended.

– Centrifugation uses centrifugal force to separate solids from liquids based on density.
– It is effective for separating very small or finely suspended insoluble particles.

Centrifugation is widely used in laboratories, industry, and medical settings (e.g., separating blood components). Other methods for separating very fine insoluble particles include filtration, but centrifugation is often faster for small particles in suspension.
