Jinsi ya kukokotoa Acid-Base Equilibrium
Acid-Base Equilibrium ni nini?
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.
Fomula
pH = -log[H+], pOH = -log[OH-], pH + pOH = 14
Mwongozo wa Hatua kwa Hatua
- 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)
Mifano Iliyotatuliwa
Ingizo
[H+] = 1.0 × 10^-7 mol/L
Matokeo
pH = 7 (neutral)
Pure water at 25°C has pH of 7
Makosa ya Kawaida ya Kuepuka
- ✕Forgetting the negative logarithm
- ✕Confusing [H+] with pH value
