Is salad dressing a mixture or pure substance?

* Mixtures are combinations of two or more substances where each substance retains its own properties.

* Pure substances are made up of only one type of molecule.

Salad dressing typically contains ingredients like:

* Oil (like olive oil or vegetable oil)

* Vinegar

* Water

* Salt

* Spices

* Herbs

These ingredients are all separate substances that are combined to create the dressing. Each ingredient retains its own properties (like oil being oily, vinegar being acidic, etc.). Therefore, salad dressing is a mixture.
