The substance to be analyzed – is white, highly soluble in water salt. Interaction with concentrated sulfuric acid leads to evolving of reddish-brown gas with pungent odour. Addition of ammonium oxalate leads to formation of white precipitate, which is insoluble in acetic acid. Diphenylamine reaction turns color of the solution to violet. What kind of salt is this? Ca(NO3) 2 NaNO2 KBrO3 MgCl2
