The letters pH stand for "power of hydrogen" and the numerical value is defined as the negative base 10 logarithm of the molar concentration of hydrogen ions. pH = -log10[H+]

WebTechnically, the pH scale measures the logarithmic concentration of hydrogen (H+) and hydroxide (OH-) ions, which make up water (H+ + OH- = H20). When both types of ions are in equal concentration, the pH is 7.0 or neutral. Below 7.0, the water is acidic (there are more hydrogen ions than hydroxide ions). WebA pH meters measures the concentration of the hydrogen ions [H+] in a solution. An acidic solution has far more positively charged hydrogen ions in it than an alkaline solution,so it has greater potential to produce an electric current under certain conditions. A pH meter takes advantage of this and work like a typical voltmeter.
