pH and pOH Calculations
pH Calculation
pH = -log[H⁺]
Calculating pH from hydrogen ion concentration
pOH Calculation
pOH = -log[OH⁻]
Calculating pOH from hydroxide ion concentration
Relation
pH + pOH = 14
The sum of pH and pOH at 25°C is 14
Concentration
[H⁺] = 10⁻ᵖᴴ
Calculating H+ concentration from pH
