Answer :
Final answer:
Salad dressing is an example of a colloid, where fine particles of one substance are dispersed in another substance.
Explanation:
An example of a colloid is salad dressing. A colloid is a mixture where one substance is dispersed as very fine particles in another substance. In the case of salad dressing, oil is dispersed in vinegar or another liquid, resulting in a cloudy appearance. Salt water is not a colloid because the salt particles are dissolved at the molecular level and not dispersed as separate particles. Homogenized milk, on the other hand, is a colloid because the fat droplets are dispersed in the milk, giving it a creamy appearance.
