Causes and Effects of Consumer Culture In the mid-nineteenth century‚ the global business market had been improved by the introduction of mass production and management for the industries. With the increase of income and level of education‚ the consumers had higher purchasing power to fulfill their needs as well as their desire (Miller 1981‚ quoted in Featherstone 1991‚ 172).

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
