nothing, they separate already because water is polar and oil is nonpolar
Nothing, because they are immiscible and can be separated by using a separating funnel.
Allow the mixture to sit until the oil and water have separated. Then pour off the oil.
Oil and water separate because oil will float to the top and water will sink to the bottom. The reason oil wil float to the top because oil is non polar while water is compound polar. Separation by decantation and filtration.Separation by decantation and filtration.
A mixture of oil and water is heterogeneous. Oil naturally separates from water and they can be separated by skimming the surface off the water.
oil and water will naturally separate over time because oil is less dense than water
Your question is very vague. Anything can be separate from water. Perhaps you mean to ask what does not mix with water. Oil would be an example.
it looks milkyish and brown
Oil and water seperate spontaneoulsy.
No. That is why oil and water separate.
Add some amount of copper sulphate(CuSO4) in the mixture. the water molecules get attracted to CuSO4 molecules and it will turn into blue colour(CuSO4.5H2O) The oil will be in normal colour so you can differentiate them.
IDEA I've never mixed them (and don't see why I should), but since Vaseline is petroleum based, you may be able to add water, dissolve the sugar, let the water and oil separate, and then boil off the water.
put oil onit
Distillation.
Add water, separate the water from the sand. Let the water evaporate.

Oil naturally separates from water and then may be skimmed off the top. For further purification, heating the oil allows the remaining water to evaporate.
