Explanation:
Vinegar and oil have different densities, as such we expect the two substances to separate when mixed. However, oil constitutes the organic phase(water insoluble) while vinegar constituents the aqueous phase since it is water soluble. Therefore, the two substances separate into layers when left to stand for a while.
The structure of lecithin makes it a good emulsifier. Hence, it can be able to cause oil and vinegar to mix, constituting a single phase when lecithin is stirred in.
