Why Is Water Insoluble In Water Polar
Water is polar. It has a positive and a negative charge. It is attracted to interacts with other polar substances and breaks the bonds holding them together; thus dissolving them. Non-polar molecules, on the other hand, do not attract the water. The water does not interact with them but rather is attracted more to itself. This is why the non-polar molecules are insoluble in water. "Like dissolves like" is usefule in that it helps us to remember that polar disolves polar. Pouring salt into water is an example of a soluble substance. Water is polar and NaCl is polar. Generally, metals are an example of substances that are insoluble in water.
