WebbpH is defined as the negative logarithm of H + ion concentration. Hence the meaning of the name pH is justified as the power of hydrogen. We know that all the acids and bases do not react with the same chemical compound at the same rate. Some react very vigorously, some moderately while others show no reaction.

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 than not, these have a "log" button. Visa mer There are several ways to define acids and bases, but pH specifically only refers to hydrogen ion concentration and is applied to aqueous(water-based) solutions. When water dissociates, it yields a hydrogen ion and a hydroxide.
