Applying Bancroft's highly empirical formulation rule, what exactly determines whether a mechanical — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Bancroft's rule dictates that the continuous phase of an emulsion is strictly determined by the solubility of the emulsifier. If an emulsifier (like normal soap) is highly soluble in water, water becomes the continuous medium, heavily promoting the formation of an Oil-in-Water (O/W) emulsion.
