Kraft temperature is the temperature:

Options

  1. Abelow which the aqueous solution of detergents starts freezing.
  2. Bbelow which the formation of micelles takes place.
  3. Cabove which the aqueous solution of detergents starts boiling.
  4. Dabove which the formation of micelles takes place.

Correct answer

D. above which the formation of micelles takes place.

Step-by-step solution

(i) Micelles formation take place only above a particular temperature called as kraft temperature ( T K ) (ii) Concentration above which micelle formation become appreciable is critical micells concentration
