Question

give any six differences between lyophilic colloids and lyophobic colloids​

Answer 1

Answer:

Lyophilic colloids

1) Disperse phase has high affinity for dispersion medium

2) They are easily formed by direct mixing or on heating.

3) They are reversible in nature.

4) They are quite stable and are not easily coagulated.

5) The surface tension of these sols is less than that of dispersion medium.

6) Lyophilic colloids are liquid loving colloids

Lyophobic colloids

1) Disperse phase has low affinity for dispersion medium.

2) They cannot be prepared directly. They can be prepared by special methods.

3) They are irreversible in nature.

4) They are unstable and are easily coagulated by adding a small amount of suitable electrolyte.

5) The surface tension is nearly same as that of dispersion medium.

6) Lyophobic colloids are liquid hating colloids
