The ph scales
WebbThe 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 + ]. Webb19 sep. 2024 · The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times …
