WebTo calculate the pH you can use the equation: pH= -log[H3O+]. In case of HCl (very strong acid) you can assume that it is 100% ionised in H2O. Therefore, pH= -log (molarity). WebMar 16, 2024 · PH is defined as the negative of the base-ten logarithm of the molar concentration of hydrogen ions present in the solution. The unit for the concentration of hydrogen ions is moles per liter. To determine pH, you can use this pH to H⁺ formula: \small\rm pH = -log ( [H^+]) pH = −log( [H+])
