The Gold number of four protective colloids A, B, C and D are 0.03, 0.003, 10 and 30 resp. protective power of these colloids will be in the order

View answer and explanation

Correct option: A

B > A > C > D

Option A (B > A > C > D) is correct because the gold number is inversely proportional to the protective power of a colloid. A lower gold number indicates higher protective power.
