Calculates the balance between acids and bases in chemical solutions using pH and pOH. This tool helps chemists, students, and lab professionals determine hydrogen ion concentrations, solution acidity, and buffering capacity.
Formel
pH = -log[H+], pOH = -log[OH-], pH + pOH = 14
Steg-för-steg-guide
- 1Measure or know the hydrogen ion concentration [H+]
- 2Apply the logarithmic pH formula
- 3Calculate pOH from the relationship pH + pOH = 14
- 4Determine if solution is acidic (pH < 7), basic (pH > 7), or neutral (pH = 7)
Lösta exempel
Ingång
[H+] = 1.0 × 10^-7 mol/L
Resultat
pH = 7 (neutral)
Pure water at 25°C has pH of 7
Vanliga misstag att undvika
- ✕Forgetting the negative logarithm
- ✕Confusing [H+] with pH value
