False Statement: c) Silver solution can form macro-molecular colloids

Explanation:

Macro-molecular colloids are a type of colloidal dispersion where the dispersed phase consists of large molecules or macro-molecules. These macro-molecules can be natural or man-made polymers. Let's analyze each option to identify the false statement:

a) Protein solution is an example of macro-molecular colloids
- This statement is true. Proteins are large macro-molecules that can form colloidal dispersions. Examples include albumin in blood plasma, gelatin, and casein in milk.

b) Man-made macro-molecules like polythene can form macro-molecular colloids
- This statement is true. Man-made polymers like polythene (polyethylene) can form macro-molecular colloids. These colloids can be formed by dispersing polythene particles in a suitable medium.

c) Silver solution can form macro-molecular colloids
- This statement is false. Silver solution forms a different type of colloidal dispersion known as a multi-molecular colloid or association colloid. In a silver colloid, the dispersed phase consists of tiny silver particles, not large macro-molecules.

d) These are normally of lyophilic type
- This statement is true. Macro-molecular colloids are typically of the lyophilic type, which means they have a strong affinity for the dispersion medium. Lyophilic colloids are stable and can form easily without the need for any special conditions or additives.

In conclusion, the false statement is c) Silver solution can form macro-molecular colloids. Silver solution forms a different type of colloidal dispersion called a multi-molecular colloid, not a macro-molecular colloid.
