The type of emulsion formed depends uponA. the relative amounts of the two liquidsB. nature of the emulsifying agentC. both of theseD. none of these |

Answer» Correct Answer - C 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. |
