Procedure

28.78 grams of molybdenum oxide (MoO3) were dissolved in a mixture of 72 ml of water and 36 ml of concentrated ammonium hydroxide, added to a solution of 97 grams of bismuth nitrate pentahydrate in ~184 ml of water and 30 ml of concentrated nitric acid with stirring, and the pH of the resulting mixture was adjusted to between 3 and 6.5 using ammonium hydroxide whereafter it was boiled for approximately 3 hours. The precipitate was filtered and washed with approximately 1000 ml of water.

Workup

  1. filtrationThe precipitate was filtered
