Answer:
Lyophilic colloids are colloids where the particles have a strong affinity for the liquid it is dispersed in. ... Typically they can be prepared simply by mixing the particles with the liquid, sometime with the addition of heat. They are purified using ultra-filtration, dialysis, and ultracentrifugation.
