4 Colligative
CHXII05:SURFACE CHEMISTRY

320923 Identify the incorrect statement:

1 Values of colligative properties of colloidal solution are of small order compared to values of true solution.
2 Tyndall effect is observed only when diameter of the dispersed particles is not much smaller than wavelength of incident light.
3 Colour of colloidal solution depends on the wavelength of light scattered by the dispersed particles
4 Brownian movement is due to balanced bombardment of molecules of dispersion medium on colloidal particles.
CHXII05:SURFACE CHEMISTRY

320924 Among the following, correct statement is :

1 Sols of metal sulphides are lyophilic.
2 Brownian movement is more pronounced for smaller particles than for bigger particles.
3 One would expect charcoal to adsorb chlorine more than hydrogen sulphide.
4 Hardy Schulze Law states that bigger the size more is the coagulation.

320925 The simplest way to check whether a system is colloid or not is

1 Tyndall effect
2 Brownian movement
3 Electrodialysis
4 Finding out particle size
