Water is a polar molecule (H2O)
Ice, penguins, polar bears, aurorae, ...
Examples: butter, vegetable oils, diesel fuel.
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
Cyclohexanone and benzophenone are both non-polar. Water is polar. "Like dissolves like" so non-polar substances dissovle other non-polar substances and polar substances dissolve other polar substances.
Generally not. The general rule to go by is like dissolves like. Polar substance will dissolve other polar substances while nonpolar substances will dissolve other nonpolar substances.
Polar solutes, including ionically bonded ones that can dissociate in the solvent.
Non-polar substances have no charges (nonionic) while polar substances have charges (ionic)
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
Because it is hydrophilic...."water-loving." Examples of these are sugars, salts and ions. :)
nonpolar
In general, polar molecules. Oil, a no polar substance, does not dissolve in water.
Because it is an intermediate polar-nonpolar solvent
Like dissolves like meaning that a polar substance will dissolve a polar substance and nonpolar substance will dissolve other polar substances. By contrast nonpolar and polar substances will not dissolve one another.
