How do emulsifiers stabilise emulsion ? Name two emulsifiers.

Text Solution

Verified by Experts

Emulsifying agent is concentrated at the interface (e.g., soap molecules, RCOONa, acting as emulsifying agent are concentrated on the surface of the deop of oil with R prat in oil and `COO^(-)Na^(+)` part in water, As a result, interfactal tension between oil and water decreases. Hence, they are intermixed into each other to form a stable emulsion.
