Buffer Calculators for Acetate Solutions and Dilutions

Use these calculators to prepare chemical solutions and work out the concentrations needed for an acetate buffer. The Acetate Buffer Composition calculator helps you determine the mixture of components for a target buffer, while C1V1 = C2V2 finds the volume of a stock solution needed to make a dilution. These tools are useful for chemistry students, researchers, and lab technicians preparing solutions for experiments. Enter your known concentrations and volumes to plan a mixture or check a dilution before you make it.

Acetate Buffer Composition

Enter a target pH and total buffer strength in mM to estimate the acetic acid and sodium acetate trihydrate needed for an acetate buffer. Results are given as % w/v.

Henderson–Hasselbalch

Calculate the pH of an acid–base buffer from the pKa and the amounts of acid and conjugate base, or find the base-to-acid ratio needed to hit a target pH. Enter pKa and concentrations to get the result instantly.

Ionic Strength

Calculate the ionic strength of a solution from the molar concentration and charge of each dissolved ion. Enter up to six ion species and get I in mol/L, plus each ion's contribution.

Buffer Capacity

Calculate buffer capacity (β) from the concentrations of a weak acid and its conjugate base, the pKa, and the pH. Enter the acid and base concentrations, pKa, and target pH to get β in mol/L per pH unit, the effective buffering range, and a strength assessment.
