How to Use This Calculator
- Enter the pH value of your solution (range 0-14).
- Review the hydrogen ion concentration [H+] in mol/L.
- Check pOH (14 - pH) and hydroxide ion concentration [OH-] in mol/L.
- pH < 7 is acidic, pH = 7 is neutral, pH > 7 is basic.
- Use for chemistry homework, water quality analysis, or buffer preparation.
