Question

A. Consider three possible ways in which Cu²⁺ could sorb to a hematite surface: (1) outer-sphere sorption, (2) inner-sphere sorption, and (3) precipitation as a Cu(II)-hydroxide. Describe the differences in the coordination environment - i.e. identify of the nearest atomic neighbours and interatomic distance within 0.5 nm (5 Å) of a given Cu(II) ion - of each sorption process. You are welcome to draw a schematic illustration to help clarify your text.

Which is correct for polarography? I-polarography is an amperometry method conducted with a dripping Hg electrode. II-The diffusion current in the plateau region of the polarographic wave is proportional to the concentration of the analyte and is used for quantitative analysis. III-The half-wave potential is characteristic of the analyte in a given environment and can be used for qualitative analysis. IV-fresh Hg drops provide reproducible results. V-polarography is primarily used to study oxidations, Hg can be reduced when studying reductions
