Write one difference between each of the following:
(i) Multimolecular colloid and Macromolecular colloid
(ii) Sol and Gel
(iii) O/W emulsion and W/O emulsion

Explanation

(i) `{:("Multimolecular colloid","Macromlecular colloid"),("They are formed by the aggregation of a large number of atoms or molecules having diameter less than 1nm. e.g.: sols of gold","They are molecules of large size. eg: polymers like rubber"):}`
(ii) `{:("SOL","Gel"),("Dispersed phase = solid","Dispersion medium = liquid"),("Dispersion phase = liquid","Dispersion medium = solid"),("eg: Muddy water","eg.: Cheese, butter"):}`
(iii) `{:("O/W emulsion","W/O emulsion"),("Oil is dispersed phase and water is dispersion medium eg: vanishing cream","Water is dispersed phase and oil is dispersion medium eg: butter and cold cream"):}`
