WebWhen two immiscible solvents are mixed, the less dense solvent makes up the top layer, while the more dense solvent makes up the bottom layer. Consider mixing either diethyl ether (d = 0.71 g/mL) or dichloromethane (d = 1.33 g/mL) with water (d = 1.00 g/mL) as shown in figure 1. When water is mixed with a less dense immiscible solvent, water WebOil and Water. The classic example of immiscible liquids is oil and water. Water is very polar; the positive hydrogen end of the molecule forms especially strong hydrogen bonds with the negative oxygen end of another water molecule. Oil in this example can be any liquid fat or even motor oil. Oil is a non-polar molecule, so when you put the two ...
