How to Use This Calculator
  1. Enter acid molarity, acid volume (mL), base molarity, and acid and base valences.
  2. Review Equivalence Volume of Base (mL) and Acid Moles.
  3. Use the equivalence volume to know exactly how much titrant to add for neutralization.

What each input means

Acid Molarity
Molar concentration of the acid solution being titrated
Acid Volume
Volume of acid solution in the flask
Base Molarity
Molar concentration of the base titrant in the burette
Acid Valence (nₐ)
Number of H⁺ ions per acid molecule (e.g., HCl=1, H₂SO₄=2)
Base Valence (n_b)
Number of OH⁻ ions per base molecule (e.g., NaOH=1, Ca(OH)₂=2)

How this is calculated

Formula

Mₐ × Vₐ × nₐ = M_b × V_b × n_b

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Acid Molarity = 0.1, Acid Volume = 50, Base Molarity = 0.1, Acid Valence (nₐ) = 1 = 5 input(s) provided
  2. Calculate Equivalence Volume
    Equivalence Volume
    50 = 50
  3. Calculate Acid Moles
    Acid Moles
    0.005 = 0.005
  4. Calculate Base Moles at Equiv.
    Base Moles at Equiv.
    0.005 = 0.005
