Explain how thermometric titrations are different than classical titrations. Discuss their advantages.
(b) What is the principle of differential scanning calorimetry (DSC)? Draw the schematic diagram of a DSC instrument.
Thermometric titrations differ from classical titrations in that they measure the temperature change during a chemical reaction rather than relying on a color change of an indicator. In a thermometric titration, the heat evolved or absorbed in the reaction between the titrant and analyte is ___ ______ _________ ________ _____ ______.
