Q. If gold number of $A, B, C$, and $D$ are $0.005, 0.05, 0.5$, and $5$ respectively, then which of the following will have the highest protective power.

Surface Chemistry

Solution:

Protective power $\propto \frac{1}{\text { Gold number }}$

Gold number of $A$ is least, therefore, it has the highest protective power.
