1.	Differentiate between the following pairs:Macromolecular colloids and multimolecular colloidsPeptisation and coagulationElectrophoresis and electrodialysis.
Answer» 1. In macromolecular collides particles are of large enough size hence can form colloid easily. These are usually polymers. On the other hand, in multimolecular colloids the smaller particles aggregated together to come in colloidal range e.g. sulphur sol, gold sol etc. 2. Peptisation: The process in which freshly prepared precipitate into colloidal sol by shaking it with suitable electrolyte in dispersion medium. On the other hand, in coagulation colloidal system get precipitated out and get settled. 3. In electrophoresis particles of dispersed phase on passing electricity move toward electrode of opposite charge and causes coagulation. When the process of dialysis that is, removing dissolved substance from a colloidal solution is carried out under applied electric field, it is known as electrodialysis.
