3. Differentiate between peptization and coagulation.
1. Due to the formation of chemical bond between adsorbate and adsorbent.
2. 4% solution of nitro cellulose in a mixture of alcohol and ether.
3. Peptisation is the process of converting a precipitate into colloidal sol by adding an electrolyte. Rut coagulation is the settling of colloidal particles
