Cara Menghitung Acid-Base Equilibrium
learn.whatIsHeading
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.
Rumus
pH = -log[H+], pOH = -log[OH-], pH + pOH = 14
Panduan Langkah demi Langkah
- 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)
Contoh Terpecahkan
Masukan
[H+] = 1.0 × 10^-7 mol/L
Hasil
pH = 7 (neutral)
Pure water at 25°C has pH of 7
Kesalahan Umum yang Harus Dihindari
- ✕Forgetting the negative logarithm
- ✕Confusing [H+] with pH value
