A) A hydrophilic colloid is a colloid is which there is a strong attraction between the dispersed phase and water
B) A hydrophobic colloid is a colloid in which there is a lack of attraction between the dispersed phase and water
C) Hydrophobic sols are often formed when a solid crystallizes rapidly from a chemical reaction or a supersaturated solution
D) All of the above
Correct Answer: D
Solution :
| [d] |
| (1) Hydro (aqueous solvent) and philic (loving): colloids have strong interactions with the dispersion medium and colloids \[-\] True |
| (2) Hydro (aqueous solvent) phobic (hating): colloids have lack of attraction for solvents and are less stable \[-\] True |
| (3) Hydrophobic soles do not pass into colloidal sol readily. A solid crystallizes rapidly form a chemical reaction or a supersaturated solution, a hydrophobic sol is formed \[-\] True. |
