Only a narrow range of pH change can be sustained by a living organism, any further change in pH can make the living difficult. For example: in the case ofacid rain, the pH of water is less than 7. As it flows into a river, it lowers the pH of river water which makes the surviv...

You may have heard that citrus juices are acids or that ammonia is a base. The terms acid and base refer to the concentration of hydrogen ions (pH) in the substance; acids have a high concentration of hydrogen ions, while bases have a low concentration o
Furthermore, 12 M HCl may not fully dissociate in aqueous solutions, and therefore, the absolute pH may be higher than the pH theoretically calculated from acid molarity. The definition of pH and its measurement is well-developed for aqueous solutions; however, the determination of pH in non-...
