The answer has to do with solubility properties.
Vinegar is polar, making it hydrophilic (water-loving). Therefore, they can interact with water, giving the appearance of mixing or dissolving. Oil is non-polar and hydrophobic (water-fearing). Therefore, it will not "mix" with water or vinegar.

∙ 12y agoOil molecules are non-polar (has no separation of positive and negative charge). In contrast, vinegar molecules are polar (separation of positive and negative charges). Since the charges contained in the vinegar molecules have no opposite in the oil molecules, they will not combine.
(Note: The inability to combine the two can be overcome by using an emulsifier, which is a substance that will react with both substances, in effect bringing them together. [Ex. washing laundry - with just water some stains are left behind; add detergent, which is an emulsifier, and the dirt now joins with the water and is removed from the laundry])

∙ 11y agoVinegar is a solution of water and acetic acid... both of which are polar. Oil is non-polar. Hydrogen bonding between the -OH groups of water and acetic acid allow for their miscibility, but no such bonds can be formed between either water or acetic acid and oil which is hydrophobic. When polar molecules get near non-polar molecules they line up nice and neat with the H atoms facing away from the polar molecule. This significantly reduces the entropy of the mixture. So, to maximize entropy, surface area of the oil must be reduced to as little as possible. For this reason, oil collects together to present the smallest surface area possible thereby maximizing entropy... and incidentally, since oil is lighter... it floats on top.

I need a list of miscible and immiscible liquids.?
immiscible oil and water copper and cobalt
What are the examples of immiscible liquids?
immiscible - oil and water miscible - water and ethyl alcohol
What is immiscible?
Immiscible liquids do not mix with each other and don't form homogeneous mixtures. An example of this type of relationship is between water and oil (they separate)
Is a heterogeneous mixture oil and vinegar air vinegar in water sugar water?
Oil and vinegar is a heterogeneous mixture.
Which is a heterogeneous mixture vinegar and water milk oil and vinegar air?
oil and vinegar
Why does an oil and vinegar dressing have two layers?
As these liquids are immiscible
Is vinegarette an emulsion?
Yes it is since it is a mixture of two immiscible compounds, oil and vinegar.
What is miscible and immiscible?
Miscible liquids are liquids that form a homogeneous mixture when they are added together. Obviously liquids that are immiscible do not form a homogeneous mixture when they are added together.
Does using an emulsifier with vinegar and oil create a chemical reaction?
No, using an emulsifier with vinegar and oil does not create a chemical reaction. An emulsifier helps to create a stable mixture of two immiscible substances, like vinegar and oil, by dispersing the oil droplets throughout the vinegar. This is a physical process, rather than a chemical reaction.
I need a list of miscible and immiscible liquids.?
immiscible oil and water copper and cobalt
Can water mix with oil?
No, they are immiscible. I want to improve the answer: Though oil and water are immiscible normally but they can be made immiscible by use of suitable surfactants or better say emulsifying agents resulting in the formation of mixture of oil and water called as emulsion.
What two liquids are immiscible?
oil and petrol
Acetone and oil miscible or immiscible?
miscible
Are water and oil immiscible?
Yes, because water is polar and oil is non-polar. So they don't mix at the particle level, which is what immiscible means.
Is oil and Methylene chloride immiscible or miscible?
they are miscible :)
What are immiscible substances?
Immiscible means incapable of mixing, but you'd (you might) have to ask further incase there is a special solution called 'immiscible solution' of which its inability to mix is only one aspect of it.
Do olive oil mix with water?
Water and olive oil are not miscible.
