Multimolecular colloids
Macromolecular colloids
1) formed by aggregation of large number of atoms of smaller radii.
1) Formed by particles of large size.
2) Low molecular masses
2) High molecular masses.
3) Weak van there waals forces
3) Strong van there waals Forces
4) Ex-sols of gold and sulphur.
4) Ex-Nylon, starch.
Associated colloids- They formed by aggregation of large number of ions. instead of atoms or molecules in above two colloids. They have van there waals force directly proportional to concentration of ions. Ex- Soap Sol.
