OBJECTIVES

  1. Run X-ray Diffraction of 2:1 Clay-α-Fe2O4
  2. Calculate the amount of Na+ ions in the 2000ppm SO42- solution
  3. Calculate the amount of Cu2+ ions in the 2000ppm SO42- solution
  4. Calculate the amount of Na+ ions in the 20ppm SO42- solution
  5. Calculate the amount of Cu2+ ions in the 20ppm SO42- solution

Na+ and Cu2+ Ion Calculations in 2000ppm SO42- Solutions

Na+ and Cu2+ Ion Calculations in 20ppm SO42- Solutions

Notes:

  • An additional 2-3 mL H2O was added to each solution to aid the dissolving of the PVOH
  • Heat was reduced when solutions began to boil too rapidly
  • While transferring solutions to Teflon dishes, loss of sample within the small beakers (sample loss = incomplete sample transfer)
