WebTesten Sie den pH-Wert verschiedener Flüssigkeiten wie Kaffee, Speichel oder Seife, um zu bestimmen, ob sie sauer, basisch oder neutral sind. Visualisieren Sie die relative Anzahl der Hydroxid-Ionen und Hydronium-Ionen in der Lösung. Wechseln Sie zwischen logarithmischen und linearen Skalen. Untersuchen Sie, ob eine Veränderung des Volumens oder … WebCalculate pH of HCl using pH equation Because HCl is a strong acid, it dissociates completely to H + and Cl - ions in the water. HCl → H + + Cl - According to the stoichiometric ratios, H + concentration equals to the HCl concentration. Therefore, we can directly substitute HCl concentration to pH equation. pH = -log 10 [H +(aq)]
