1. In which phase of the emulsion is oleic acid found for the BP formula? Support your conclusion by referencing the relevant results.
2. What role in the emulsion do oleic acid and dilute ammonia solution play for the BP formula? Support your conclusion by referencing the relevant results.
3. Draw likely interaction/s of oleic acid and dilute ammonia solution to achieve this role in the BP formula (this can be inserted as an image for submission).
