Phosphorus oxide (P4O10) → Stannic chloride pentahydrate

Participants

Reaction Steps

Approximately 6500 ml of distilled water was heated to about 80 degrees C. Approximately 30 g of P2O5 was dissolved in 250 ml of concentrated HCl, then an additional 125 ml of HCl was added. A solution of SnCl4.5H2O in 2000 ml of distilled water was prepared which contained about 0.445 g SnO2 /ml. A solution of TaCl5 in concentrated HCl was prepared which contained about 0.19M TaCl5. The TaCl5, SnCl4 and P2O5 solutions were mixed together in a beaker.
