There are polar and nonpolar substances. The more polar a substance, the more it dissolves in polar, the more nonpolar the more in nonpolar.

Water is polar and dissolves well in salt, which is also polar.

Oil is nonpolar and dissolves well in petrol, which is also nonpolar.

However, oil dissolves badly in water as they are not the same in the sense.

The solution of a substance in a solvent requires an interaction between the two.

Now polar substances interact in principle differently than nonpolar substances. Therefore, although polar substances are “compatible” with one another and nonpolar substances are also, but polar and nonpolar, this does not work properly. Because they don’t interact.

Fats are, for example, nonpolar substances. You can release them wonderfully in oil because oil is also nonpolar. But to release fat in water, you will not get down because water is polar.

And saline is a wonderful example of a polar substance that dissolves water perfectly in the polar solvent… but try to dissolve salt in nonpolar oil. Doesn’t work.

When you tilt water to water, the water dissolves in the water. If you turn oil into the water, the oil will not dissolve. It will swim up
