pH to moles per liter
Type a value in pH to get it in mol/L instantly.
1×10⁻⁷mol/L
That's about the acidity of pure water. Neutral, near pure water and blood.
Convert the other way: mol/L to pH
What it means
How acidic is that?
Values are for water at 25 °C. The neutral point shifts slightly with temperature: it is 6.14 in water at 100 °C.
The math
How to convert pH to mol/L
pH is a logarithm: pH = −log₁₀[H⁺], and going back, [H⁺] = 10^(−pH) moles per liter. pOH is the mirror image, since pH + pOH = 14 in water at 25 °C.
Example: 7 pH = 1×10⁻⁷ mol/L.
