One way to classify emulsions is by identifying the continuous and dispersed phase of the emulsion. Continuous phase is the liquid in which another liquid is dispersed. In other words, it is the dominant phase in the emulsion. Dispersed phase is the opposite. It is the liquid that is dispersed within the continuous phase and which therefore occupies a relatively small space in the emulsion compared to the continuous phase.
Based on this method of classification there are three major types of emulsions: O/W(Oil in Water), W/O(Water in Oil), and bicontinuous (where both water and oil have equal share in the emulsion). In this experiment, we will create different emulsions and observe what physical characteristics they exhibit and whether or not there is a more stable way to form an emulsion, that is, so that the emulsion stays emulsified for a long time without separating. After that, we will plot the characteristics on the phase diagram to estimate what ratios of water,oil, and surfactant will create the most stable emulsion.
