Hydrogen Ion Concentration Calculator
Result
Hydrogen Ion Concentration Calculator The Hydrogen Ion Concentration Calculator converts a pH value into the molar concentration of hydrogen ions [H+], and also shows the hydroxide concentration [OH-]. — free online calculator.
Formula
- Hydrogen Ion Concentration Calculator calculates its result from Ph. It uses the formula [H+] = 10^(-pH); [OH-] = 10^(-(14 - pH)). Change any input to recalculate the result instantly.
- The main inputs are Ph. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Hydrogen Ion Concentration
- Ph: 3
Using Ph = 2, the calculated result is 1.0000000000e-12.
