How Titration Calculations Work

Formula

C_a = (C_t × V_t × n_a) / (V_a × n_t)

Where:

  • C_a = concentration of analyte
  • C_t = concentration of titrant
  • V_t = volume of titrant at equivalence point
  • V_a = volume of analyte
  • n_a, n_t = stoichiometric coefficients
  • At the equivalence point, moles of titrant and analyte are in stoichiometric ratio.

    Example Calculation

    50 mL of unknown HCl is titrated with 0.1 M NaOH; 25 mL NaOH is used to reach equivalence.

    1. 01C_a = (C_t × V_t × n_a) / (V_a × n_t)
    2. 02C_a = (0.1 × 25 × 1) / (50 × 1)
    3. 03C_a = 2.5 / 50
    4. 04C_a = 0.05 M
