Dissolving Liquids in Water
Science Background:
· Liquids have characteristic properties based on the molecules they are made of.
· The properties of liquids depend on the attractions the molecules of the liquid have for each other and for other substances.
· Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids.
· Polar liquids, like water, dissolve other liquids which are polar or somewhat polar.
· Polar liquids, like water, do not dissolve nonpolar liquids like oil.
