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 could be soluble in soap?
A.
ammonia, which is a polar substance with four slightly charged atoms
B.
vegetable oil, which is a nonpolar substance with atoms that share electrons equally
C.
both because soap is part polar and part nonpolar

Ammonia, because it’s a polar molecule, will get attracted to the hydrophilic end while the vegetable oil (non-polar) will interact with the hydrophilic end. Both, therefore have the capacity to dissolve in soap due to the amphipathic properties of soap.

Explanation:

Soap can be categorized as having amphipathic properties. Soap can be composed of fatty-acid chains co-joined with sodium/potassium ions. The fatty acid chains act as hydrophobic ends while the fatty acid acts as the hydrophilic end. This is why soap is a good washing agent The hydrophilic end attached to the ‘dirt’ that needs to be washed away, while the hydrophilic end interacts with the water molecules. Rinsing then washes away the soap including the ‘dirt’.
