Step 1
B ionic head dissolves in water, non-polar tail dissolves in oil droplet
Answer
The correct description of the ball-like structures formed when soap is added to an oil and water mixture is option B. In this scenario, the ionic (hydrophilic) head of the soap molecules interacts favorably with the water, allowing it to dissolve, while the non-polar (hydrophobic) tail, which is repelled by water, dissolves in the oil droplet. This creates a structure that organizes itself with the tails inward, forming a micelle, while the heads are exposed to the aqueous phase.
