Why milk is soluble in water and oil is insoluble in water?

Answer 1

Oil and water separate because water is a polar compound and oil is a non polar compound. Or, water has a positive charge on one side of the compound and a negative charge on the other side. It mixes with compounds with charges on one side. Oil does not have any electric charges. It only mixes with a compound that has no electric charges.
Oil separates from water for two reasons. First of all, it is electrically repelled from water because the lipid molecules that comprise oil are electronically well balanced whereas water is highly polar. The result is that no part of the lipid is attracted to either electric pole of the water molecule. Despite this, oil and water can be combined via agitation (such as mixing a vinaigrette). However, oil is less dense than water and will eventually float to the top of the oil/water mixture.

Answer 2

Oil has a differenty density so usually oil will (vegetable oil or car oil?) stay at the top while water sinks to the bottom, water and milk have almost equal densities so it's easier for them to mix.

Answer 3

This is due to the density of the oil mainly. It is much less dense than water and floats on top. Another thing is oil molecules are hydrophobic (they do not mix with water, and are repelled away). This can be overcome by the use of an emulsifier molecule. This is a molecule which has a hydrophobic end, and a hydrophilic (water loving) end. They pull the oil and water throughout the mixture.

Answer 4

When you mix oil and water the oil rises to the top. Oil and water do not mix together because of their make up, so when you put oil in water, the oil will rise to the top of the water.

Answer 5

Oil is insoluble in water because oil is non-polar and water is polar. This means that their charges don't attract one another.

Answer 6

because oil has more fluid than water and more gas
