Ayala is making salad dressing. She mixes oil and vinegar in a blender until a smooth consistency is formed. Explain whether this is a heterogeneous or a homogeneous mixture and why.

Answer:

Ayala’s salad dressing is a heterogeneous mixture. This is because oil and vinegar do not dissolve in each other. A homogeneous mixture, or solution, can only form when the substances are capable of dissolving into one another. Because the oil and vinegar stay separate as tiny droplets rather than dissolving, the mixture remains heterogeneous.
