1.	Which of the following is false regarding macro-molecular colloids?(a) Protein solution is an example for macro-molecular colloids(b) Man-made macro-molecules like polythene can form such colloids(c) Silver solution can form macro-molecular colloids(d) These are normally of lyophilic typeThis question was posed to me in exam.I would like to ask this question from Surface Chemistry in section Surface Chemistry of Chemistry – Class 12
Answer» Right choice is (c) SILVER solution can form macro-molecular COLLOIDS Best explanation: Macro-molecules DISSOLVE in a suitable solvents, gives rise to PARTICLES of colloidal SIZE. These are normally of lyophilic type and silver solution is an example for lyophobic and multi-molecular colloids.
