AI Generated Solution

To determine the order of protective powers of the colloids A, B, C, and D based on their gold numbers, we can follow these steps: ### Step 1: Understand the relationship between gold number and protective power The protective power of a colloidal solution is inversely proportional to its gold number. This means that a lower gold number indicates a higher protective power. ### Step 2: List the gold numbers of the colloids - Gold number of A = 0.04 - Gold number of B = 0.002 ...
