Buffer Capacity Calculator (Van Slyke Equation)
Calculate buffer capacity (β) to quantify a solutions resistance to pH change upon addition of strong acid or base.
Input Parameters
Instant Real-time CalculationThe Van Slyke buffer capacity beta represents the moles of strong acid or base required to change the pH of one liter of buffer by 1 unit. Buffer capacity reaches its theoretical maximum when pH = pKa.
