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

Morioka Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Date Performed: April 25‚ 2013; Date Submitted: April 30‚ 2013 Alkyl halides could be synthesized through several processes and using different compounds as reactants. One of the simplest method used is the addition of a hydrogen halide to an alcohol. In this research‚ tert-butyl alcohol was reacted with cold concentrated HCl to produce tert-butyl chloride. The crude product was distilled

Acoustic Theory and Synthesis Frequency: Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20‚000Hz. As the cycles per second increases‚ the smaller the wavelengths become‚ therefore there is a higher frequency which will cause
