SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of

Blood is a necessary component of the majority of living organisms (all vertebrates and some invertebrates); it carries vital nutrients‚ oxygen and proteins to body tissues and carries away waste products. Blood‚ although most commonly red‚ can also be found in such colours as green‚ blue‚ clear‚ pink and violet. However‚ the common misconception surrounding the idea that human blood is blue before oxygenation is false. All human blood is varying shades of red; these wild alternate colours are

Peter Debye and his Contributions to Chemistry Abstract Dutch physicist Peter Debye studied under Arnold Sommerfeld‚ and developed several approaches using induced dipole moments and x-ray diffraction to study molecular structures. In 1912 he exhibited the Debye equation for dipole moments‚ a method to determine bond angles and the degree of polarity of covalent bonds‚ which allows the spatial configuration of molecules to be deduced with far greater accuracy than had previously
