Advanced pH Calculator
Calculate pH, pOH, [H⁺], and [OH⁻] with detailed explanations
About pH Calculations
pH Formula
pH = -log₁₀[H⁺]
Where [H⁺] is the hydrogen ion concentration in moles per liter (mol/L).
pOH Formula
pOH = -log₁₀[OH⁻]
Where [OH⁻] is the hydroxide ion concentration in moles per liter (mol/L).
Relationship
pH + pOH = 14 (at 25°C)
[H⁺] × [OH⁻] = 1.0 × 10⁻¹⁴
Solution Types
- pH < 7: Acidic
- pH = 7: Neutral
- pH > 7: Basic (Alkaline)
