From a terminology standpoint, water is more correctly referred to as the chemical compound hydrogen hydroxide since it has the OH hydroxyl ion in combination with the H ion. Other common hydroxides are calcium (CaOH), sodium (NaOH), and potassium (KOH) hydroxides. Hydroxides are moderate to strong basic compounds and react violently with acids to form water and a salt giving off a lot of energy in the process. For example NaOH reacts with hydrochloric acid (HCl) to produce water (hydrogen hydroxide) and sodium chloride (NaCl). The pH of water is neutral because the negative charge on the OH ion is balanced by the positive charge on the H ion. Hydrogen hydroxide is an extremely stable compound because of the bonding and shape of the molecule. That's why it takes so much energy to separate hydrogen from the oxygen in water.
