What is difference between multimolecular and macromolecular colloids?
Answers
Answer:
Definition
Multimolecular Colloids: Multimolecular colloids are particles formed by the aggregation of smaller molecules when they are dissolved in a solvent.
Macromolecular Colloids: Macromolecular colloids are individual particles that are large enough to be considered as colloids.
Dimensions
Multimolecular Colloids: Multimolecular colloids are formed from particles having diameters less than 1 nm.
Macromolecular Colloids: Macromolecular colloids are formed from particles having diameters in the colloidal range (around 100 nm).
Molecular weight
Multimolecular Colloids: Multimolecular colloids are formed from particles having low molecular weights.
Macromolecular Colloids: Macromolecular colloids are formed from particles having high molecular weights.
Formation
Multimolecular Colloids: In the formation of multimolecular colloids, when the compound is added to a dispersion medium, small molecules form aggregates having dimensions in the colloidal range.
Macromolecular Colloids: In the formation of macromolecular colloids, when the compound is added to a dispersion medium, compound separates into individual molecules which have their dimensions in colloidal range.
Nature
Multimolecular Colloids: Multimolecular colloids have a lyophobic nature.
Macromolecular Colloids: Macromolecular colloids have a lyophilic nature.
Forces
Multimolecular Colloids: The aggregates in multimolecular colloids are held together via weak Van der Waal forces.
Macromolecular Colloids: There are strong attraction forces between particles and the liquid in macromolecular colloids.
