How to Calculate Both the Hydrogen & Hydroxide Ion Concentration for a Solution.?

Answer

1. Multiply the solution's pH by -1. For example, if the solution has a pH of 10.14: 10.14 - -1 = -10.14. 2. Raise 10 to the power of this value: 10^10.14 = 7.244 - 10^11. This is the solution's hydrogen ion concentration, measured in moles per
