The pH of human blood ranges from 7.35 to 7.45 with it usually being around 7.40. If the blood pH gets below 7.35 a person goes into acidosis. If the pH gets above 7.45 a person goes into alkalosis. Both acidosis and alkalosis can be fatal. How much more acidic is a person’s blood if it has a pH of 7.3 compared to its preferred 7.4? How much more alkaline is a person’s blood if it has a pH of 7.6 rather than its preferred 7.4?
