Emulsification test

When oil and water, which are immiscible, are shaken together, the oil is broken up into very tiny droplets which are dispersed in water. This is known as oil in water emulsion. The water molecule due to the high surface tensions have tendency to come together and form a separate layer. This is why the oil and water emulsion is unstable in the presence of substances that lower the surface tension of water (sodium carbonate, soap, bile salts etc.) The tendency of the water molecule to coalesce is decreased and the emulsion becomes stable. Since bile salts cause the greatest decrease in surface tension they are best emulsifying agents.
