Synthesize precursor molecule K8[BW11O39H]·13H2O


  • Added 150.1220 g of Na2WO4·H2O and 10.0560 g of Boric Acid to 250 mL of boiling water.
  • Added ~95 mL of 6 M HCl with vigorous stirring until the pH was 6.
  • Boiled solution for 1 hour
  • Solution volume and pH were monitored closely during boiling and DI water was added periodically to make up for lost volume.
  • The solution was cooled to room temperature
  • Solution was stored overnight at 4°C


A clear and colorless solution was obtained with some minor precipitate present.
