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

Insulin is a hormone synthesized exclusively

The attack of "conscience" that King Richard suffers in Act 5‚ Scene 5 of Shakespeare’s Richard III (133-157) can be seen as the psychological climax of the drama‚ one that is critical to both Richard’s development as a character and the play’s ultimate success.
