Question

Soap is made of molecules with atoms that share electrons equally at one end and atoms that have a slight charge at the other end. Which of the following could be soluble in soap.

a.vegetable oil
b.water
c.ammonia
d.all of the above.

Answer 1

Soap is amphiphilic with a hydrophobic tail and a hydrophilic head; it can dissolve vegetable oil, water, and ammonia. The correct answer is d. all of the above.

Step-by-step explanation:

Soap molecules are unique in that they have a hydrophobic tail and a hydrophilic head, making them amphiphilic. This dual nature allows soap to dissolve in both oil and water, making it an effective cleaning agent. Soap's hydrophobic (water-fearing) tail is non-polar and is attracted to non-polar substances like vegetable oil, while its hydrophilic (water-loving) head is polar and dissolves in water. Ammonia, being a polar molecule, would also interact with the polar end of soap. Therefore, the substances that could be soluble in soap are vegetable oil due to its non-polarity, water and ammonia because of their polarity. The correct answer to the question is d. all of the above.

Answer 2

Out of the choices given here, the one that could be soluble in soap is ammonia. The other choices are not soluble in soap. This will make the correct answer C.
