Which part of the diagram shows a sediment?


Salad dressing is a mixture of multiple substances, similar to the food coloring mixture we separated.
Oil and vinegar are two ingredients in almost all salad dressings. We will refer to these as our base ingredients.
-Substances DO NOT DISAPPEAR!
-If you SEE sediment, the substance did not dissolve. If you DO NOT SEE sediment, the substance dissolved.
- Watch the video to see if the substance (ingredient) dissolves or does not dissolve
