 Sodium Orthovanadate Preparation Am 18.04.2009, 15:57 Uhr, schrieb Lionel Brooks 3rd <[Only registered users see links. ]>: There seems to be an impurity. Adding a spatula of activated charcoal before the first boiling and filtering afterwards might help. There may also be a trace of phosphate present, wich gives a yellow tint (or precipitate, if the concentration is high enough). Make sure that you have pure reagents and that the glassware is free of phosphate (detergent!)  |
