Show full solutionCorrect option: C
Correct answer
CA < C < B < D
Step-by-step explanation
For a protective colloid lesser the value of gold number better is the protective power.
Thus the correct order of protective power of and is
Gold number
Hence is the correct answer
Thus the correct order of protective power of and is
