How does water emulsified in oil behave when mixed with water?

Water emulsified in oil behaves differently than water mixed with oil. When water is emulsified in oil, it forms small droplets that are suspended in the oil, creating a stable mixture. When this emulsified mixture is subsequently mixed with water, the behavior largely depends on the characteristics of the emulsion and the phases involved.

The correct answer indicates that the mixture remains thick and does not disperse. This is because the emulsified water droplets still exist within the oil phase and do not easily separate into the water phase. The presence of oil creates a barrier that inhibits the mixing of these tiny water droplets with the larger body of water. Instead of dispersing evenly, the emulsified mixture tends to remain separate and maintain a thick consistency due to the presence of the oil surrounding the dispersed water droplets.

In the context of the other options, while some emulsions might have limited solubility, they generally do not mix readily or become clear, as full integration of water and oil is not achievable in this scenario. Therefore, the behavior of the emulsified water is characterized by its persistence in the oil phase, leading to a thick and non-dispersing mixture when combined with water.
