Het waterstofion of volgens de IUPAC hydron (H ) is het kation van waterstof. Vaak wordt hierbij in de chemie gedoeld op het waterstofion van de isotoop H (protium), dus een proton, maar de andere isotopen van waterstof hebben hun eigen ionen. Een klein percentage (0,015 %) van het in de natuur voorkomende waterstof is deuterium ( H); het kation van deuterium is het deuteron. Natuurlijk… Web18 sep. 2024 · When NH3 reacts with H+ ions, it produces NH4+ and leaves OH- ions in the solution. Because the concentration of OH- ions rise with the rise in pH, it imparts basicity to the solution. The formed ammonium ion (NH4+) also keeps breaking into NH3 and H+ ions, and thus not all NH3 results in the formation of OH- ions, and thus NH3 is … WebSachez ce que c'est que le pH.

The characteristic process time does not change significantly and is in the range of 2.5–5 h. The analysis enables to determine the equilibrium uptakes of H+- and OH− -ions. These follow the expected U-shaped path across the pH-range.
