Calculate pH
About pH
pH is a measure of the acidity or basicity of an aqueous solution. It's defined as the negative logarithm of the hydrogen ion concentration.
pH = -log[H⁺]
Key relationships:
- pH + pOH = 14 (at 25°C)
- pH < 7: Acidic solution
- pH = 7: Neutral solution
- pH > 7: Basic solution
Henderson-Hasselbalch Equation (Buffers):
pH = pKa + log([A⁻]/[HA])
Weak Acid pH:
pH = ½(pKa - log[HA])
pH is crucial in chemistry, biology, medicine, and environmental science for understanding solution properties and chemical behavior.
