Acid-Base & Buffers

Acid-base equilibrium calculators built around one shared idea: how a solution resists, or fails to resist, a change in pH. From pKa conversions to full buffer capacity math, these tools cover the chemistry behind why some solutions barely shift when acid is added while others swing wildly.

Buffer Capacity Calculator (Target pH)

The Buffer Capacity Calculator works out buffer capacity (beta) using the Van Slyke equation from concentration, pKa, and pH, or from measured titration data (initial and final pH plus acid/base added). Its Target Beta mode also solves the reverse problem, finding the buffer concentration needed to reach a specific capacity at a specific pH, a calculation most competing tools skip.
