Final answer:
Mustard powder adds flavor, texture, and stability to salad dressing through its interaction with other molecules. Its intermolecular forces contribute to the overall stability and texture of the dressing.
Step-by-step explanation:
Mustard powder has a role in salad dressing due to its contribution to the flavor and texture of the dressing. It contains compounds called glucosinolates, which when combined with water and enzymes, produce the characteristic pungent and spicy taste of mustard. These compounds also contribute to the thickening of the dressing, creating a smoother texture.
In terms of intermolecular forces, the glucosinolates in mustard powder interact with the other molecules in the dressing through electrostatic interactions. These intermolecular forces help bind the different components together and contribute to the overall stability and texture of the dressing.
