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.

Công thức

pH = -log[H+], pOH = -log[OH-], pH + pOH = 14

Hướng dẫn từng bước

  1. 1Measure or know the hydrogen ion concentration [H+]
  2. 2Apply the logarithmic pH formula
  3. 3Calculate pOH from the relationship pH + pOH = 14
  4. 4Determine if solution is acidic (pH < 7), basic (pH > 7), or neutral (pH = 7)

Ví dụ có lời giải

đầu vào
[H+] = 1.0 × 10^-7 mol/L
Kết quả
pH = 7 (neutral)
Pure water at 25°C has pH of 7

Lỗi thường gặp cần tránh

  • Forgetting the negative logarithm
  • Confusing [H+] with pH value
