WebbWhile the pH scale typically runs from 0 to 14, it is definitely possible to calculate a negative pH. A negative pH occurs when the molarity of hydrogen ions in a strong acid … Webb31 jan. 2024 · pH 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.
WebbSummary. The pH of blood refers to how acidic it is. The typical pH for blood in the arteries is 7.35 to 7.45.
