Distinguish betwen Lyophobic colloid and Lyophilic colloids:
| Lyophobic colloids |
Lyophilic collids |
| (i) They are easily precipitated by addition of a small amount of suitable electrolyte. |
They are quite stable and are not easily precipited or coagulated |
| (ii) They are irrevirsible in nature. |
They are reversible in nature. |
| (iii) Their viscosity is almost the same as that of the medium. |
Their velocity is much higher than that of medium. |
| (iv) Their surface tension is nearly same as that of the dispersion medium. |
Their surface tension is usually lower than that of the dispersion medium. |
