Cum se calculează Acid-Base Equilibrium
Ce este Acid-Base Equilibrium?
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.
Formulă
pH = -log[H+], pOH = -log[OH-], pH + pOH = 14
Ghid pas cu pas
- 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)
Exemple rezolvate
Intrare
[H+] = 1.0 × 10^-7 mol/L
Rezultat
pH = 7 (neutral)
Pure water at 25°C has pH of 7
Greșeli frecvente de evitat
- ✕Forgetting the negative logarithm
- ✕Confusing [H+] with pH value
