Hcl ph value
WebMay 2, 2024 · The equilibrium equation yields the following formula for pH: pH = -log 10 [H +] [H +] = 10 -pH. In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value. It's easy to do this calculation on any scientific calculator because … WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization …
