Webb2 maj 2024 · How to Calculate pH and [H+] 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 ... WebbThe pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity. Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. (4.12) An excess of hydrogen ions makes a solution acidic, whereas a dearth of H+ ions, or an excess of hydroxyl ions, makes it basic. WebbA pH 7.0 is considered neutral.

Webb10 apr. 2024 · pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the pH scale and is t he range of values from 0 to 14 that describes the acidity or ... WebbAlkalinity (from Arabic: القلوي, romanized: al-qaly, lit. 'ashes of the saltwort') is the capacity of water to resist acidification.
