Mixtures and solutions calculators

• Alligation Calculator

  Find how much of a stronger and weaker stock to combine for a target concentration.

• Buffer pH Calculator

  Estimate the pH of an acid or base buffer using the concentrations of a conjugate pair.

• Dilution Factor Calculator

  Calculate the final-to-stock dilution factor and distinguish it from the diluent-to-stock ratio.

• Henderson–Hasselbalch Calculator

  Find buffer pH from pKa and composition, or find the conjugate-base-to-acid ratio required for a target pH.

• Mass Percent Calculator

  Find mass percentage from component masses, or calculate solute and solvent masses for a target mixture.

• Mixing Ratio Calculator

  Normalize up to fifteen component amounts into percentages and scale every amount by a common factor.

• Neutralization Calculator

  Calculate normality from mass and equivalent weight, or the volume required to neutralize a known quantity of acid or base.

• Percentage Concentration to Molarity Calculator

  Convert between mass percentage and molarity using solution density and solute molar mass.

• Percent Solution Calculator

  Calculate mass/volume, mass/mass, or volume/volume percentage with the denominator made explicit.

• pH Calculator

  Calculate pH, pOH, and ion concentrations from measured ions or an ideal strong or weak acid/base solution.

• Raoult’s Law Calculator

  Estimate the vapor pressure of an ideal binary solution from liquid-phase composition and pure-component vapor pressures.

• Serial Dilution Calculator

  Plan equal-factor dilution steps and see the concentration, transfer volume, and diluent needed at every stage.

• Solution Dilution Calculator

  Find the stock aliquot for a target concentration and volume, or predict concentration after dilution.
