Formation of ionic bond between Na and Cl and covalent bond in water is to be demonstrated. Concept introduction: An ionic bond is formed by electrostatic interaction between two oppositely charged ions. Ions are formed by transfer of one more electrons from one atom to another. The atom that looses electron gains positive charge is called as cation and the atom that gains electron gets negative charge is called as anion. Ionic bond is the electrostatic interaction between a cation and an anion. Covalent bonds are formed when two atoms share a pair of electrons to gain stability instead of transferring. Covalent bonds are generally formed between atoms with small or no difference in electronegativity.

(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
