Select the correct statements regarding cleansing action of soap.

Hydrophilic end of soap molecules interact with the oily droplets.
The formation of micelles in a soap solution during the cleaning of clothes is called emulsification.
The hydrophobic end of the soap molecules is in the inner side during micelie formation.
Micelles surround the Ca2 + or Mg2+ ions in hard water instead of oily droplets.

Explanation:

- Statement A: Incorrect. The hydrophilic end of soap molecules interacts with water, not oily droplets. The hydrophobic end interacts with oily substances.

- Statement B: Correct. The process where soap molecules encircle and trap oil droplets to form micelles is called emulsification.

- Statement C: Correct. During micelle formation, the hydrophobic ends orient towards the inside away from water, trapping the oil.

- Statement D: Incorrect. Micelles surround oily droplets, not ions like Ca²? or Mg²?. In hard water, these ions can inhibit soap's effectiveness.

- Option 3: B and C is indeed correct.
