The correct Answer is:
To solve the question "Soap emulsifies," we need to understand the concept of emulsions and the role of soap as an emulsifier. Here’s a step-by-step solution: ### Step 1: Understand Emulsions An emulsion is a mixture of two immiscible liquids, where one liquid (the dispersed phase) is dispersed in the other (the dispersion medium). There are two main types of emulsions: - Oil in Water (O/W) emulsion - Water in Oil (W/O) emulsion ### Step 2: Identify the Role of Soap Soap acts as an emulsifying agent. It has a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail. This structure allows soap to stabilize emulsions by reducing the surface tension between the two immiscible liquids. ### Step 3: Determine the Type of Emulsion Soap Stabilizes When soap is used as an emulsifier, it primarily stabilizes oil in water (O/W) emulsions. The hydrophilic heads of the soap molecules interact with water, while the hydrophobic tails interact with oil, allowing the oil droplets to remain suspended in the water. ### Step 4: Conclusion Based on the above understanding, we can conclude that soap emulsifies in the oil in water (O/W) type of emulsion. ### Final Answer Soap emulsifies in oil in water type emulsions. ---
