Webbind to the extra hydrogen or hydroxyl ions in water. So, for example, the more acidic a solution, the more hydrogen ions there are, and the more the color will change! A solution of water, where the H+ and OH- ions are in balance, is called neutral, and it has a pH of 7. As you add more acid (and therefore more hydrogen ions), the pH goes down. WebEvaluation of calcium ion, hydroxyl ion release and pH levels in various calcium hydroxide based intracanal medicaments: An in vitro study Calcium hydroxide with sterile water and RC Cal pastes liberate significantly more calcium and hydroxyl ions and raise the pH higher than Metapex and calcium hydroxidegutta-percha points.
