Question

A salad dressing is prepared with oil, vinegar, and chunks of blue cheese. Is this a homogeneous or heterogeneous mixture?

1) Homogeneous
2) Heterogeneous

Answer 1

It’s a Heterogeneous mixture.

Answer 2

A salad dressing made with oil, vinegar, and blue cheese is a heterogeneous mixture because its composition is not consistent throughout and contains visibly distinct ingredients.

Step-by-step explanation:

A salad dressing prepared with oil, vinegar, and chunks of blue cheese is considered a heterogeneous mixture. This type of mixture is characterized by a composition that is not uniform throughout. In a heterogeneous mixture, elements of the mixture such as oil and vinegar may separate, and the chunks of blue cheese are visibly distinct particles within the mixture.

This contrasts with a homogeneous mixture, in which the composition is uniform throughout, such as in a commercial sports drink. Examples of other heterogeneous mixtures include Italian dressing, chocolate chip cookies, and granite. Each of these has components that can be seen separately and whose distribution throughout the mixture is not consistent.
