John Cuthber Posted November 22, 2009 Share Posted November 22, 2009 Are you trying to dispose of it? If so the simplest solution is to take it somewhere away from people and buildings etc and set fire to it carefully. Obviously you need to do this somewhere where a fire will not uspet anyone. The official way would be to get some hazmat company to take it away. Link to comment Share on other sites More sharing options...

rosegay Posted November 22, 2009 Author Share Posted November 22, 2009 hosphorus is very poisonous, 50 mg constituting an approximate fatal dose. Exposure to yellow phosphorus should not exceed 0.1 mg/m3 .i want to know how can we turn the impure yellow phosphorus into H3PO4 in a safe way,also simple to carry out Link to comment Share on other sites More sharing options...
adianadiadi Posted November 22, 2009 Share Posted November 22, 2009 Use nitric acid to oxidise it to phosphoric acid. But first try with small samples in safe conditions like in fume cupboard. Other way is to burn it and then add water. But it is not so easy. Link to comment Share on other sites More sharing options...
