Paano Kalkulahin si Acid-Base Equilibrium
Ano ang 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.
Pormula
pH = -log[H+], pOH = -log[OH-], pH + pOH = 14
Step-by-Step na Gabay
- 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)
Mga Nalutas na Halimbawa
Input
[H+] = 1.0 × 10^-7 mol/L
Resulta
pH = 7 (neutral)
Pure water at 25°C has pH of 7
Mga Karaniwang Mali na Dapat Iwasan
- ✕Forgetting the negative logarithm
- ✕Confusing [H+] with pH value
