As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic. Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic.

Webb4 maj 2024 · The pH Equation. To calculate pH all you need is the H + ion concentration and a basic calculator, because it is a very straightforward calculation. The H + ion concentration must be in mol dm-3 (moles per dm 3).. pH = -log [H +]. The key is knowing the concentration of H + ions, and that is easier with strong acids than it is with weak …
