pH Calculator

1. Input: Concentration of H+ ions (in mol/L).
2. Convert: Alternatively, calculate pH from pOH or [OH-].
3. Result: See the pH value.

The pH Calculator determines the acidity or alkalinity of a solution based on the concentration of hydrogen ions [H+].

pH = -log[H+]. A pH below 7 is acidic, 7 is neutral, and above 7 is basic. Vital for biology, swimming pool maintenance, and food science.
