WebNov 13, 2024 · In water, a base will produce or donate a hydroxide ion, OH-, which has a charge of -1. A base has a bitter taste and a pH of more than 7 on the pH scale. Acids and bases can range from weak to ... 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 more often ...
