In-depth explanation of Titrimetric Analysis
Titrimetric analysis, also called volumetric analysis, determines the amount of an analyte by measuring the volume of a standard reagent needed to react with it completely. The titration is carried out until the endpoint, signalled by a colour change or an instrumental response, is reached, and the endpoint should lie as close as possible to the equivalence point. Titrations are classified as acid-base, redox, precipitation or complexometric according to the type of reaction. The reaction must be rapid, stoichiometric and have a clear endpoint, and the titrant must be standardized. Titrimetry is accurate, fast and inexpensive for many routine determinations.
Going deeper: Titrimetric Analysis
Key ideas: At equivalence, moles of titrant times its stoichiometric factor equals moles of analyte. For a 1:1 reaction C1V1 = C2V2. Do a rough titration first, then add dropwise near the endpoint, swirling continuously. Take at least three concordant titres within 0.10 mL and average them, ignoring the rough one. Choose the indicator whose transition range lies on the steep part of the curve.
Common mistakes and connections: Students use the initial burette reading incorrectly, subtract the wrong way, forget the stoichiometric ratio (such as 2 NaOH per H2SO4), or include an outlying titre in the mean. Endpoint and equivalence point are not identical, and the difference is the indicator error. Over-titrating cannot be undone. Related to standard solutions, indicators, pH curves and uncertainty.
Visualization of Titrimetric Analysis
The pH jumps sharply at equivalence when 0.1 M strong base is added to 25 mL of 0.1 M strong acid, which the endpoint should match closely. The interactive lesson shows this as a live animation or chart.
Worked example and use case
The vitamin C content of a tablet is determined by titration with a standard iodine solution.
