Because it is non-polar itself.
Remember the addage : Like Dissolves Like.
Polar solvents dissolve polar solutes. And non-polar solvents dissolve non-polar solutes.
They have similar attractive forces in their molecule.
Some lipids are non-polar. But most are polar. :3
you know water is a polar substance and can solve only polar substances and ionic substance it is not able to solve fat , oil or other organic (usually) substances (oil). by ionic substance I meant substances such as salt
Because water molecules have partially charged atoms.
it is able to dissolve or eat away at other substances such as metal , skin or bones.
Ethanol is polar, and so is water. "Like dissolves like," so those two liquids will be miscible, meaning they will dissolve each other. Carbon tetrachloride, meanwhile, is non-polar. Its intermolecular forces are incompatible with water's, so polar water will not be able to dissolve it.
Water is a polar covalent molecule. The partial charges in the molecule attract other charges, ionic or more partial charges from other covalent molecules and dissolves them. Nonpolar bonded molecules have no partial charges and the water molecules will attract each other thus not attracting the nonpolar and does not dissolve them.

Two non-polar substances share similar attractive forces in their molecules, which is what enables them to dissolve in each other. The dissolving medium in a solution is referred to as a solvent.
The difference in the electronegativity of oxygen and water pulls the bonded electrons closer to the oxygen atom than the two hydrogen atoms. This creates a dipole moment (a charge separation along the bond), leaving the oxygen with a partial negative charge, and the hydrogen with a partial positive charge. This is known as a "polar" molecule", and will dissolve other polar substances. With the exception of homo-nuclear diatomics (N2, O2, etc.) all molecules contain at least some degree of polarity, and therefore are able to dissolve in a polar substance. Because water is very polar, it tends to dissolve other highly polar substances ("like dissolves like") extremely well, and will even dissolve molecules that are considered "non-polar" (but they still have a small dipole moment), albeit to a lesser extent.
No.Water can't dissolve non-polar molecules. Water is a polar molecule. Since polar molecules can only dissolve with polar molecules, and non-polar molecules can only dissolve with non-polar molecules, water and non-polar molecules don't react together. Exception:- Some very small non-polar molecules can dissolve in water, like oxygen (O2)
There are basically two types of solvents, polar and non-polar. This refers to the electrical charges in a molecule; polar molecules have positive and negative poles, non-polar molecules don't. The most familiar polar solvent is water, familiar non-polar solvents would be such things as gasoline, cooking oil, etc. So, polar substances dissolve in polar solvents, and non-polar substances dissolve in non-polar solvents. A polar substance will not dissolve in a non-polar solvent. Soap is a chemical that has both polar and non-polar elements to its molecular composition, and therefore is able to bridge the gap between polar and non-polar.

As rule (but not general) a polar compound is dissolved in a polar solvent and inverse.
Water is also a good solvent due to its polarity. Substances that will mix well and dissolve in water (e.g. salts) are known as hydrophilic (water-loving) substances, while those that do not mix well with water (e.g. fats and oils), are known as hydrophobic (water-fearing) substances. The ability of a substance to dissolve in water is determined by whether or not the substance can match or better the strong attractive forces that water molecules generate between other water molecules. If a substance has properties that do not allow it to overcome these strong intermolecular forces, the molecules are pushed out from the water, and do not dissolve. Contrary to the common misconception, water and hydrophobic substances do not repel, and the hydration of a hydrophobic surface is energetically, but not entropically, favorable
If you're referring to chemical polarity, then water is a common polar substance. It's polar because at the particle level, a water molecule has a positive end and a negative end (caused by unshared electrons between hydrogen and oxygen.) As a result, water is able to dissolve many other substances which are also polar (like salt.)
Both have polar molecules.
Ethanol is polar, and so is water. "Like dissolves like," so those two liquids will be miscible, meaning they will dissolve each other. Carbon tetrachloride, meanwhile, is non-polar. Its intermolecular forces are incompatible with water's, so polar water will not be able to dissolve it.
