The balanced equation for the preparation of hydrogen peroxide, by treating barium peroxide with sulphuric acid, is to be represented. Concept introduction: Oxygen is the first element of Group 16 (according to modern periodic table). The atmosphere contains about 21% molecular oxygen. Oxygen has two allotropes— O 2 and O 3 Oxygen forms oxides, peroxides, and superoxides. Peroxides contains O 2 2 − ion. The basicity of oxides increases on moving down a group. Hydrogen peroxide is completely miscible with water. Hydrogen peroxide is a colorless and syrupy liquid.

(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
