1
Q
lyophilic colloids
A
contain chemical groups that interact strongly with the
solvent, creating a sheath of solvent molecules that prevent solute/solute
interactions. Very common in biological systems and in foods
2
Q
lyophobic colloids
A
contain chemical groups that interact weakly with the
solvent. These colloids are all inherently unstable; they will eventually
coagulate.
Ex) Oil emulsions or glacially-produced rock dust in river water
3
Q
stabilization by cloaking
A
A lyophobic colloid can be made to masquerade as
lyophilic by coating it with something that itself possesses suitable lyophilic
properties.
