Chart:
Water is an excellent solvent of ionic and polar substances because it is a polar liquid.

How to reference this medium
Solubility in water often depends strongly on the temperature; solids and gases behave differently. The higher the temperature the less soluble gases are in water, solids however tend to dissolve better at higher temperatures (there are several exceptions, such as lithium sulfate).
Information and ideas:
Normally a substance is more soluble in polar solvents such as water, the more polar groups that substance has. Near-critical water however has similar solubility properties as non-polar organic solvents. The temperature dependency of solubility is a good example for looking at the difference between speed and equilibrium.
