A) Part A is the sediment
B) Part B is the 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
