Colloids:
Colloids are the mixtures in which the size of the particles is intermediate between those of true solutions and suspensions. The particles of colloids are not visible to the naked eye but can be seen under an ultramicroscope.
Correct statement(s) related to colloids are:
B) Colloidal solution freezes at a higher temperature than the true solution at the same concentration. This is because the particles in the colloidal solution have a larger surface area than the particles in the true solution, which results in more energy being required to freeze the colloidal solution.
C) Surfactants form micelle above critical micelle concentration (CMC). CMC depends on temperature. The surfactant molecules in the solution arrange themselves in a spherical structure called a micelle when their concentration reaches a certain level known as the critical micelle concentration (CMC). The CMC depends on the temperature of the solution.
The other statements are incorrect:
A) The process of precipitating colloidal sol by an electrolyte is called peptization. This is incorrect as peptization is the process of converting a precipitate into a colloidal sol by adding a suitable electrolyte.
D) Micelles are macromolecular colloids. This is incorrect as micelles are not macromolecular colloids. They are aggregates of surfactant molecules that form a spherical structure in a solution.
In conclusion, the correct statements related to colloids are that colloidal solutions freeze at a higher temperature than true solutions at the same concentration and that surfactants form micelles above the critical micelle concentration, which depends on temperature.

(1) Process of precipitating colloidal solution by using an electrolyte is called 'coagulation' and not peptization.
(2) Since molar mass of sol is much higher than true solutions, magnitude of any colligative properties is smaller than true solutions.
So, freezing point of sols > freezing point of true solution
So, option (2) is correct.
(3) Micelles are formed at greater than or equal to CMC and above KRAFT temperature.
So, option (3) is also correct.
(4) Micelles are associated colloids and not macromolecular colloids.
