WebThe pH scale actually is based on another scale. We usually keep track of the concentration of solutes in moles per liter (M). The pH is minus the log (base 10) of the H + concentration in moles per liter. Since at room temperature in pure water, that concentration is very close to 10-7 M, pH 7 is neutral. Mike W.
