« on: February 21, 2009, 12:38:30 PM »
Hi,
                           My problem says that two masses of the gases N0 and NO2 are mixed.How do we separate them using a solution only ? We only have to Distinguish between them....
 Please help , I haven't found it any of my books. :-[

Just pass the mixture into freshly prepared FeSO4 solution. NO gets absorbed in it but NO2 does not. Then heat the solution and NO will come out of it.

FeSO4+ 6 H2O = [Fe(H2O)6]SO4

[Fe(H2O)6]SO4 + NO = [Fe(H2O)5NO]SO4
