Water's excellent solvent properties are due to its polarity. The oxygen atom has a partial negative charge while the hydrogen atoms have a partial positive charge. Due to this dipole moment, water can easily solvate many polar substances.
Water is a polar substance, which means that any other polar substances will dissolve in it.
The opposite is mineral turpentine which is non-polar so all non-polar substances dissolve in it.
Because water is polar (it has an uneven charge distribution).
The polarity of water makes it an ideal solvent for many solutions.
Its molecular arrangement.
pure water
insoluble
Giant covalent substances like diamond tend not to dissolve in anything. Non polar molecular substances such as hydrocarbons are not attracted to water.
It depends on the physical properties of the substance. Sometimes heating a hydrophobic substance can increase solubility. Also, heating may cause the substance to denature and dissolve. In the case of proteins, proteins can contain many hydrophobic parts but still be soluble in water. However, hydrophobic substances do not typically dissolve in water, due to the polar nature of water. Typically, scientists use the word "hydrophobic" only to describe substances that have a negligible solubility in water. You may have meant to ask "why do hydrophilic substances dissolve in water".
heterogeneous mixture
Polar substances are miscible (will dissolve) in each other and non-polar substances will dissolve in each other. "Like dissolves like!" Mineral oil is non-polar. Hexane is a six carbon chain and is also non-polar. Water on the other hand is polar because it contains an electronegative oxygen.

Nutilite's vitamins dissolve in water.
Salt and Sugar dissolve in water.
I'm not sure what your asking but the term for substances that are unable to dissolve in water are called unsoluable.
Water does not dissolve everything. Some substances dont mix with water. Those are hydrophobic substances, ex: oil molecules
Many different substances dissolve easily in water, but there are some which don't, particularly oily substances. Soap makes these substances dissolve in water.
In general, polar molecules. Oil, a no polar substance, does not dissolve in water.
Water is a polar substance, which means that any other polar substances will dissolve in it. The opposite is mineral turpentine which is non-polar so all non-polar substances dissolve in it.
