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.
공식
pH = -log[H+], pOH = -log[OH-], pH + pOH = 14
단계별 가이드
- 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)
풀어진 예시
입력
[H+] = 1.0 × 10^-7 mol/L
결과
pH = 7 (neutral)
Pure water at 25°C has pH of 7
피해야 할 일반적인 실수
- ✕Forgetting the negative logarithm
- ✕Confusing [H+] with pH value
