Webb29 mars 2024 · pH is the negative logarithm of the concentration of: hydrogen ions magnesium ions potassium ions calcium ions WebbBecause the pH scale is logarithmic, there is a 10-fold difference between each unit. For example, pH 5 is 10 times as acid as pH 6 and pH 4 is 100 times as acid as pH 6. The general mathematical formula defining pH is: pH = -log [H+], in which pH is the negative logarithm of the hydrogen ion concentration.

Webb9 aug. 2024 · The pOHof a solution is the negative logarithm of the hydroxide-ion concentration: \[\text{pOH} = -\text{log} \left[ \ce{OH^-} \right]\nonumber \] The pH of a solution can be related to the pOH. Consider a solution with a pH \(= 4.0\). The \(\left[ \ce{H^+} \right]\) of the solution would be \(1.0 \times 10^{-4} \: \text{M}\).
