Classification of Colloids
CHXII05:SURFACE CHEMISTRY

320781 The solubility of lyophilic colloids is due to

1 Charge on their particles
2 A layer of dispersion medium on their particles
3 The smaller size of their particles
4 The large size of their particles
CHXII05:SURFACE CHEMISTRY

320782 Which is lyophobic in nature?

1 Gelatin
2 Phosphorus
3 Starch
4 Agar-Agar
CHXII05:SURFACE CHEMISTRY

320783 The stabilisation of a lyophobic colloid is due to:

1 The viscosity of the medium.
2 The formation of a covalent bond between two phases.
3 The large electrokinetic potential developed in the colloid.
4 Preferential adsorption of similar charged particle on colloids surface.
CHXII05:SURFACE CHEMISTRY

320784 When a sulphur sol is evaporated sulphur is obtained. On mixing with water sulphur sol is not formed. The sol is

1 lyophilic
2 reversible
3 hydrophobic
4 hydrophilic
