The presence of soluble soap as a emulsifying agent generally forms the formation of emulsion of :
Correct answer: A. oil in water
- A. oil in water
- B. water in oil
- C. both type
- D. none
Explanation
Emulsification takes place by reduction of interfacial tension between two phases. 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

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
