The compounds that require electrolysis to yield free metals are to be determined from the given compounds. Concept introduction: Electrolysis is a purification technique. It is only possible for electropositive elements. Electropositive elements undergo electrolytic reduction as they are strong reducing agents. The reduction takes place on the halide of the metal or anhydrous molten oxide. Some electropositive elements are not suitable for electrolytic reduction because of their solubility.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³
