- Consider the following series of poly(phenylene oxide) polymers A–D, and their glass transition temperatures. Explain how the differences in structure can account for the differences in Tgwrite a summary of each of the techniques for measuring vacancyconcentrations, noted therein. (1) Measurements of the quenched-in residual electricalresistivity of aluminium rapidly cooled from temperatures be-low about 800 K with initial quenching rates of 2 × 106 K s−1give the enthalpy of formation of monovacancies H F1V =(0.65 ± 0.01) eV.(2) Comparison of the quenching data with high-temperature differential-dilatometry data gives the monova-cancy formation entropy SF1V = (0.76 ± 0.4)kB (kB =Boltzmann’s constant) and the low-temperature resistivity perunit concentration of vacancies ρ1V = (1.9 ± 0.1) μm.(3) The binding enthalpy of divacancies in Al is H B2V =(0.17 5 ± 0.02 5) eV. This is in agreement with earlier ex-perimental determinations by Doyama and Koehler 48) and byLevy et al. 49, 50) but in marked contrast to the claim of Carlinget al., 23) based on computations with the generalized gradi-ent approximation, that in Al H B2V is zero or even negativeand therefore the…Give some of the application of Coloumetry, Potentiometey, Electrogravimetry and Voltammetry in different fields.
- discuss the importace and methods of solid liquid separation processes of hydro metallurgyDiscuss glass transition temperature and the factors affecting GTT and what are its significances. Give detailed answer pleaseThe chief chemist of the Brite-Metal Electroplating Co. isrequired to certify that the rinse solutions that are discharged from the company’s tin-plating process into the municipal sewer system contain no more than 10 ppm (parts per million) by mass of Sn2+. The chemist devises the following analytical procedure to determine the concentration. At regular intervals, a 100-mL (100-g) sample is withdrawn from the waste stream and acidified to pH = 1.0. A starch solution and 10 mL of 0.10 M potassium iodide are added, and a 25.0-mA current is passed through the solution between platinum electrodes. Iodine appears as a product of electrolysis at the anode when the oxidation of Sn2+ to Sn4+ is practically complete and signals its presence with the deep blue color of a complex formed with starch. What is the maximum duration of electrolysis to the appearance of the blue color that ensures that the concentration of Sn2+does not exceed 10 ppm?
