How can the two emulsions can be distinguished : (a) oil in water type (o/w) and (b) water in oil type (w/o)

So is reproduction a defining property? Then what about sterile organisms?

[Hint : For o/w emulsions : Proteins, gums, soaps. For w/o emulsions : Fatty acids, long chain alcohols, lampblack.]

[Hint : Physisorption arises because of van der Waal’s forces, not specific and reversible while chemisorptions is caused by chemical bond formation, highly specific and irreversible.]

(a) False (b) True (c) True (d) True (e) True (f) True
