Question

11. At concentration below CMC, the
surfactant molecules remain;
O A. Above the surface of water
O B. At water- air interface
O C. In the bulk of water
O D. Uniform in bulk and interface​

Answer 1

Answer:

d number is the answer of this question

Answer 2

At concentration under CMC, the surfactant molecules continue to be uniform in bulk and interface​

Explanation:

• CMC is a vital micelle concentration associated with surfactant molecules and it forms micelles.
• These micelles assist in getting rid of dirt, grease, dirt, etc from clothes.
• The formation of micelles takes place best above a selected temperature known as Kraft temperature and above a particular concentration known as critical micelle concentration (CMC).
• At CMC the numerous surface molecules associate to shape a colloid and that is known as as Associated colloids.
