Answer 1

Answer:

CMC- Critical Micelle Concentration

Explanation:

• The critical micelle concentration (CMC), in colloidal and surface chemistry, is the concentration of surfactants above which micelles develop and all further surfactants added to the solution will also produce micelles. 

• An essential quality of a surfactant is its CMC. Surface tension significantly varies with surfactant concentration before it reaches the CMC.
• Surface tension either stays largely constant after passing the CMC or changes to a lower slope.
• Temperature, pressure, the presence and concentration of additional surface active compounds and electrolytes, as well as the dispersant in question and the media in which it is dispersed, are all factors that affect the CMC value. Only above the critical micelle temperature do micelles develop.
