Titrimetric methods were not well received by the analytical chemists of that era because they could not duplicate the accuracy and precision of a gravimetric analysis. Not surprisingly, few standard texts from the 1700s and 1800s include titrimetric methods of analysis. Precipitation gravimetry developed as an analytical method without a general theory of precipitation. An empirical relationship between a precipitate’s mass and the mass of analyte— what analytical chemists call a gravimetric factor—was determined experimentally by taking a known mass of analyte through the procedure. Today, we recognize this as an early example of an external standardization. Gravimetric factors were not calculated using the stoichiometry of a precipitation reaction because chemical formulas and atomic weights were not yet available! Unlike gravimetry, the development and acceptance of titrimetry required a deeper understanding of stoichiometry, of thermodynamics, and of chemical equilibria. By the 1900s, the accuracy and precision of titrimetric methods were comparable to that of gravimetric methods, establishing titrimetry as an accepted analytical technique. 411 412 Analytical Chemistry 2.0 9A Overview of Titrimetry We are deliberately avoiding the term In titrimetry we add a reagent, called the titrant, to a solution contain- analyte at this point in our introduction ing another reagent, called the titrand, and allow them to react.

ABSTRACT Almost every monocrystalline silicon solar cell design includes a wet chemical process step for the alkaline tex- turing of the wafer surface in order to reduce the reflection of the front side. The alkaline texturing solution contains hydroxide, an organic additive usually 2-propanol and as a reaction product silicate. The hydroxide is consumed due to the reaction whereas 2-propanol evaporates during the process. Therefore, the correct reple- nishment for both components is required in order to achieve constant processing conditions. This may be sim- plified by using analytical methods for controlling the main components of the alkaline bath. This study gives an overview for a successful analytical method of the main components of an alkaline texturing bath by titration, HPLC, surface tension and NIR spectrometry.

  • Isothermal Titration Calorimetry and Differential Scanning Calorimetry As Complementary Tools to Investigate the Energetics of Biomolecular Recognition
    JOURNAL OF MOLECULAR RECOGNITION J. Mol. Recognit. 1999;12:3–18 Review Isothermal titration calorimetry and differential scanning calorimetry as complementary tools to investigate the energetics of biomolecular recognition Ilian Jelesarov* and Hans Rudolf Bosshard Department of Biochemistry, University of Zurich, CH-8057 Zurich, Switzerland The principles of isothermal titration calorimetry (ITC) and differential scanning calorimetry (DSC) are reviewed together with the basic thermodynamic formalism on which the two techniques are based. Although ITC is particularly suitable to follow the energetics of an association reaction between biomolecules, the combination of ITC and DSC provides a more comprehensive description of the thermodynamics of an associating system. The reason is that the parameters DG, DH, DS, and DCp obtained from ITC are global properties of the system under study. They may be composed to varying degrees of contributions from the binding reaction proper, from conformational changes of the component molecules during association, and from changes in molecule/solvent interactions and in the state of protonation.
