Soap molecules form micelles around the oil droplet in such a way that:
The hydrophobic part of the stearate ions lies in the oil droplet
The hydrophobic part of the stearate ions lies out of the oil droplet.
The hydrophilic part of the stearate ions lies in the oil droplet
None of these.
Answers (1)
The cleansing action of soap is due to the fact that soap molecules form micelle around the oil droplet in such a way that the hydrophobic part of the stearate ions is in the oil droplet and the hydrophilic part projects inside the grease.
Since polar groups can interact with water, the oil droplet surrounded by stearate ions is now pulled in water and removed from the fabric. Thus soap helps in emulsification and washing away of oil and fats.
Therefore, option number (1) is correct.
