0.00245 eq
How to Use This Calculator
Measure titrant data
Standardize your titrant, then record the concentration and volume consumed to reach the endpoint.
Record analyte volume
Measure the sample (analyte) volume added to the titration vessel.
Include valence factors
For polyprotic acids or redox reactions, note the number of equivalents per mole involved.
Read analyte concentration
The tool reports the unknown analyte concentration along with the equivalents consumed.
Formula
C₁ V₁ n₁ = C₂ V₂ n₂
C is concentration (mol/L), V is volume (L), and n is the number of equivalents per mole. Rearranging solves for the unknown concentration or volume.
Example
24.50 mL of 0.100 M NaOH (n = 1) neutralizing 25.00 mL of acid (n = 1) gives C_acid = (0.100 × 0.02450) / 0.02500 = 0.0980 M.
Full Description
Titration quantifies an analyte by reacting it with a titrant of known concentration until the equivalence point is reached. The stoichiometry of the reaction, expressed via equivalent factors, determines the relationship between concentrations and volumes.
This calculator aids in acid-base, redox, and precipitation titrations by computing unknown concentrations from measured titrant volumes.
Frequently Asked Questions
What if the analyte and titrant have different valences?
Set the valence factors accordingly. For example, n = 2 for H₂SO₄ or Ca(OH)₂.
How accurate is the result?
Accuracy depends on standardization of the titrant, precise volume measurement, and endpoint detection quality.
Can I solve for volume instead?
Yes. Rearrange the formula or modify the calculator inputs to treat concentration as known and volume as the unknown.
Does temperature affect titrations?
Most aqueous titrations have minimal temperature dependence, but ensure reagents and indicators are used within recommended ranges.
What endpoints are supported?
Any titration reaching an equivalence point works, provided you know the stoichiometry and valence factors.
