The type of emulsion formed depends upon

Options

A. the relative amounts of the two liquids
B. nature of the emulsifying agent
C. both of these
D. none of these

Answer

C

Explanation

If water is in excess, it is oill-in-water emulsion. If, on the other hand, oil is in excess, it is water-in-oil emulsion. Emulsions can be diluted with any amount of the dispersion medium. On the other hand, the dispersed liquid when mixed, forms a separate layer.
The presence of soluble soaps as the emulsifying agent generally favours the formation of emulsion of oil-in-water type, whereas the presence of insolube soaps (containing non-alkali metal atoms) favour the formation of emulsions of water-in-oil type.
