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 ___ _____ ________ _____ ____ _____ _________ ____ _______ _____ __________ __________.

What information does the energy dispersive spectroscopy (EDS) provide? Write any three applications of EDS.
Briefly explain the basic principle of Auger Electron Spectroscopy (AES) with a suitable diagram.
Indium and Cadmium ions in 0.1 M HCl give peaks at potentials -0.557 V and -0.597 V by differential pulse polarographic analysis. When a standard solution containing 0.4 ppm of indium is analysed, it gave peak current (in arbitrary units) corresponding to 100.25 at -0.557 V and 43.75 at -0.597 V. A standard solution containing 0.4 ppm of Cd gave ip 29.52 at -0.557 V and 64.8 at -0.597 V. What is the concentration of indium and cadmium in a sample if the peak current is 190 at -0.557 V and 120 at -0.597 V.
What is dropping mercury electrode? Give its advantages.
Explain why neutron induced reactions are most common whereas deuteron induced reactions require accelerator facility to carry out these reactions.
In a coulometric method, 200 mg of nitrobenzene in of methanol is reduced to phenyl hydroxylamine at a constant potential of -0.95 V (vs. SCE) applied to an Hg electrode. Following reaction takes 30 minutes to complete.
