This is due to the fact that the 1M solution has only a 50g difference to that of the 0.5M solution in the SI unit of 1 litre. So the MSDS will...

Hi All,

A good way (Safe as well) is to demonstrate the Phosphorus is to scoop a little in a spoon of a deflagrating spoon and igniting it with a BB. Safe and effective way for demonstrating it.

Look at things this way, if your prep room is in operation and you enter the Chemstore for retreval o...
