Answer 2

Methods for separate water from oil:

1)To separate oil from water, add a solution of soluble ionic salt to the solution. Distillation, which involves boiling and condensing the water, is another option, as well as partially freezing the oil and water combination and discarding one-fourth to one-third of the unfrozen water.

2)Changing the state of the water to either a gas or a solid is a means to cleanly remove all of the oil from the water.

3)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.

4)Use Hierarchical membrane for Separating finely mixed oil and water

MIT researchers have discovered a new, inexpensive way of getting the two fluids apart again.

Their newly developed membrane could be manufactured at industrial scale, and could process large quantities of the finely mixed materials back into pure oil and water.

In addition to its possible role in cleaning up spills, the new method could also be used for routine drilling, such as in the deep ocean as well as on land, where water is injected into wells to help force oil out of deep rock formations.
