When dissolved in water sodium hydroxide almost completely dissociates into what ions?

Iodine (I2) is an example of a non-electrolyte. This is a purple-black solid at room temperature. When heated, it turns to a gas (sublimation) producing a beautiful violet cloud. It dissolves readily in many organic solvents, producing violet solutions in most cases and yellow-brown solutions in alcohols. Iodine is not very soluble in water, but produces a slightly yellow solution. No ions are produced when iodine dissolves in any of these solvents.

NaOH dissociates into Na+ and OH- ions which results in no change
As, water also contains OH- ions as the only negative ions

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.
