Question

What are surfactants also known as?

1) Spreaders
2) Wetting agents
3) Both A and B
4) None of the above

Answer 1

Surfactants, also known as surface-active agents, are substances that disrupt the intermolecular interactions between molecules of a polar liquid, reducing its surface tension. They are used as spreaders and wetting agents.

Step-by-step explanation:

Surfactants, also known as surface-active agents, are substances such as soaps and detergents that disrupt the intermolecular interactions between molecules of a polar liquid, reducing its surface tension. They are used in various applications, including as spreaders and wetting agents. Therefore, the correct answer is 3) Both A and B.
