Given answer along with e

Check the box if you agree with the corresponding statement. In case you do not agree, leave the box empty O a. In voltammetry, electrolysis is carried out in conditions that diffusion is the fundamental process. Migration and convection are minimized by avoiding agitation and temperature gradients. O b. In an electrolytic cell besides the corresponding electrodes, salt bridge is used to prevents mixing up of analyte solution components but this type of bridge generates a considerable potential c. The alkali errors in glass electrodes are exhibited at pH > 9 and are due to the fact that electrodes respond to H+ and alkali cations. The acid errors in glass electrodes are exhibited at pH < 0.5 and are due saturation effect with respect to H+. O d. The use of low pressures and low density carrier gas, in hot zones, is a strategy to avoid thermal convection and minimize signal noise on Thermogravimetric Analysis (TGA). In TGA, in order to avoid the lag or difference between sample temperature (Ts) and furnace temperature (Tf), thus besides calibration it is recommended to operate the equipment in controlled relative low flow atmosphere and low heating rate O f. Large sample size cause problems like heat transfer, and gas exchange with the surrounding. In general, the use of small (~ 500 mg) specimen is preferable.
