WebAn acid is a substance that produces hydrogen ions, H + (aq), when dissolved in water. The higher the concentration of hydrogen ions in the solution, the lower the pH. (Higher tier) WebHydride (H: –) also reacts with metals to form chemical compounds which are reducing agents. OH – = Hydroxide ion. Hydroxide (OH–) is also known as the hydroxyl ion. When water dissociates or comes apart into its component parts it forms OH – (hydroxide ions) and H 3 O + (hydronium ions).
