Question

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 type

This 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 1

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.
