Vedclass · Answer

(A) An emulsifier is a substance that stabilizes an emulsion by preventing the dispersed droplets from coalescing. Soap acts as an emulsifier because its molecules have a long hydrocarbon tail that is hydrophobic (oil-loving) and a polar head that is hydrophilic (water-loving). When soap is added to a mixture of oil and water,the hydrocarbon tails dissolve in the oil droplets,while the polar heads remain in the water. This creates a stable emulsion where the oil droplets are dispersed in water and prevented from merging due to electrostatic repulsion between the negatively charged heads. Therefore,$Soap$ is the correct answer.
