Q. Gold numbers of protective colloids A, B, C and D are 0.50, 0.01, 0.01 and 0.005 respectively. The correct order of their protective powers is

Surface Chemistry

Solution:

Smaller the gold number, greater is the protective power. Thus protective power of $A, B, C$ and $D$ are in the order
$D (0.005)>\,B(0.01)>\,C(0.05)>\,A(0.50) $ or $A <\, C<\,B<\,D$
