Calculation Breakdown

  1. Moles of titrant delivered at the end point0.1 mol/L × 0.025 L = 0.0025 molntitrant=CtVtn_{\text{titrant}} = C_{\text{t}} V_{\text{t}}
  2. Convert to moles of analyte with the reaction ratio0.0025 mol × 1/1 = 0.0025 molnA=nTabn_A = n_T \dfrac{a}{b}
  3. Divide by the analyte volume0.0025 mol ÷ 0.02 L = 0.125 mol/LCA=nAVAC_A = \dfrac{n_A}{V_A}

What Is the Titration Calculator?

A titration calculator determines an unknown concentration from titrant data.

How Does the Titration Calculator Work?

It computes titrant moles, converts them via the stoichiometric ratio and divides by the analyte volume.

Titration Calculator Formula & Variables

The core mathematical equation utilized by this calculator is expressed as:

CAVAa=CBVBb\dfrac{C_A V_A}{a} = \dfrac{C_B V_B}{b}

Moles of titrant are found from concentration and volume, then converted to moles of analyte using the stoichiometric ratio.

How to Use the Titration Calculator

  1. Enter the titrant concentration and volume, the analyte volume and the reaction coefficients.

Step-by-Step Example Calculation

25 mL of 0.1 M titrant against 20 mL analyte

Input Values:

titrantMolarity:0.1
titrantVolumeMl:25
analyteVolumeMl:20
analyteCoefficient:1
titrantCoefficient:1
Worked Steps: The analyte is 0.125 mol/L.

Understanding Your Result
