Chapter 6: Problem 10

An emulsifier is a substance which (a) helps dispersion of liquid in liquid (b) stabilises the emulsion (c) purifies the emulsion (d) coagulates the emulsion

Short Answer

Expert verified
The correct answers are (a) helps dispersion of liquid in liquid, and (b) stabilises the emulsion.

Step by step solution

01

Understanding the role of emulsifier

An emulsifier is a substance that is capable of mixing two substances which are usually immiscible (not forming a homogeneous mixture when added together). The role of emulsifier often comes into play where it creates a stable, homogenous, and smooth mixture of water and oil
02

Analyzing the options

(a) helps dispersion of liquid in liquid: This is correct as emulsifiers do help in dispersing one liquid into another liquid which usually are immiscible. \n (b) stabilises the emulsion: This is also correct, as the primary function of an emulsifier is to stabilize the mixture of immiscible substances. \n (c) purifies the emulsion: This option is incorrect as the role of an emulsifier is not to purify the mixture but to stabilize and homogenize it \n (d) coagulates the emulsion: This is also incorrect as the function of an emulsifier is to stabilize the emulsion and not coagulate it.
03

Answer

Based on the understanding of the scientific concept of an emulsifier and analyzing the given options, it can be inferred that an emulsifier (a) helps dispersion of liquid in liquid, and (b) stabilises the emulsion, while the other two options are incorrect.
