Question
Which of the following statement is correct?
Options
A.Potassium ferrocyanide can cause greater coagulation in a basic dye as compared to Na2HPO3.
B.A starch aqua sol can act as protective colloid for Fe(OH)3
C.The slope of the Freundlich adsorption isotherm ($\log\frac{x}{m}$ vs. log P) keeps on changing for a long range of pressure and is constant over a limited range of pressure.
D.Higher the zeta potential, greater is the stability of colloid.
Solution
(a) Basic dye is positively charged and hence, $Fe(CN)_{6}^{4 -} > HPO_{3}^{2 -}$
(c) Slope should not change in Freundlich’s isotherm.
