Chicken soup is an example of a heterogeneous mixture. This means that the components of the mixture are not uniformly distributed, and you can see the distinct ingredients within the soup.
In a typical bowl of chicken soup, you’ll find pieces of chicken, vegetables like carrots and celery, and broth. Each of these ingredients can be identified separately. The solids float around in the liquid broth, and if you were to let the soup sit, you would notice that the solid ingredients could settle at the bottom. This contrasts with a homogeneous mixture, where the components are so well mixed that they appear uniform to the naked eye, like saltwater.
Therefore, because you can differentiate between the ingredients in chicken soup, it is classified as a heterogeneous mixture.
