Detection of phosphorus? - heat detection
Erlenmeyer flask in a liquid mixture of Mongo beans with 20 ml of sodium hydroxide 2%. Boil the mixture in a water bath for 30 minutes. Cool and filter through cheese cloth. Collect the filtrate into an Erlenmeyer flask. 20 ml of 10% sulfuric acid. Heat in a boiling water bath a5minutes.
5 of the clear solution ml in a test tube joint. Add 10% nitric acid until the solution is definitely acid and 3 ml of ammonium molybdate. Mix well and heat in boiling water bath. A yellow precipitate formed. They say that contain phosphorus.
This is the hardest part:
What is the purpose of following the detection of phosphorus?
Cooking with 2% sodium hydroxide
Acidification and boiling with 10% sulfuric acid
Acidification with 10% nitric acid
Additional ammonium

Many of you seem to be working in the same laboratory!
If the game is that "Google" the words "" "recognition" dat ", see this entry, including:
A critique of the nitro molybdate method for the detection ... A critical method for the detection of nitro-molybdate phosphorus in the tissues. GG Nasmith and E. Fidler. Full story ...

Not exactly the procedure, but if you read (at least the first three pages of this paper discussed below), sell similar actions in the proceedings and, and an explanation.
Hope this helps.
Good luck!
