Ph scale chemicals
WebThe pH scale is considered a logarithmic scale corresponding to the concentration of protons (H+ ions) in aqueous solutions. So, pH is the negative log of [H+] and can be calculated using the following formula: = - log 10 H +. Some textbooks use [H3O+] to refer to the concentration of protons instead of [H + ]. WebApr 26, 2024 · The pH range is from zero to 14, with zero being the most acidic, 14 being the most basic, and seven being neutral. In healthy humans, normal body pH is between 7.35 and 7.45, with an average of 7.4. 1 This slightly alkaline pH level is ideal for many biological processes, such as the oxygenation of blood.
