Equation for NaOH + H2O (Sodium hydroxide + Water)

In this video we will describe the equation NaOH + H2O and write what happens when NaOH is dissolved in water. When NaOH is dissolved in H2O (water) it will dissociate (dissolve) into Na+ and OH- ions. To show that they are dissolved in water we can write (aq) after each. The (aq) shows that they are aqueous – dissolved in water. The equation for NaOH (Sodium hydroxide) and H2O sometimes isn’t considered a chemical reaction since it is easy to change the Na+ and OH- back to NaOH (just let the H2O evaporate). At the same time, the NaOH is a very different substance than Na+ and OH-.
