Attempt to synthesize an Erbium Nitrate variant of the Desired POM.


  • Added 1.6043 g of Potassium precursor to 40 mL of DI water.
  • Added 0.91803 g of Erbium Nitrate pentahydrate to 20 mL of DI water.
  • Combined the two solutions above and adjusted the PH to 3.5 using 1 M NaOH.
  • Refluxed for 2 hours at 80 °C
  • Cooled solution to room temperature
  • Left solution mixing overnight


  • Erbium Nitrate solution was pink and clear and the potassium precursor solution was clear and colorless to start, but upon mixing, a pinkish-white precipitate formed and the solution became cloudy with (what is likely) suspended solid.
