They don't mix in water and will float. Adding impurities to the oil may make it more dense however. An example is the oil that gets drained out of cars -- it has lots of heavy metal particles suspended in it which makes it a lot more dense. But the fresh, clean oil should float in water. Vinegar is a solution of acetic acid in water. However, a typical value is 1. The oil floats on the vinegar.
When two liquids are placed in a container, the denser liquid will fall to the bottom. The less dense liquid will rise to the top. This is why oil floats above vinegar in a bottle of salad dressing before it is shaken. But to change it back to a match would be MOST difficult. However, I can put hydrogen gas and oxygen gas in a container, add a spark or a match and it explodes.
If I do this in a vessel and collect the product, which is water, then I can reverse this chemical change by electrolyzing the water back to hydrogen and oxygen gas which is another chemical change. And I can switch back and forth between the two. I hope this helps. First Name. Your Response. Acetic acid HC2H3O2 is an important component of vinegar. Am I right? Propylene Glycol.
