Background 2NaNO2(s)+ 2FeS04(aq)+3H2S04(aq)- 2NO(g)+Fe2(So4)3(aq)+ 2NaHSO4(aq)+ 2H,0() Nitrogen monoxide has a very limited solubility in water. The oxidation state of nitrogen in nitrogen monoxide(no)is +2. Since typical oxidation state of nitrogen ranges from-3 to +5, nitrogen monoxide has both oxidising and reducing properties with suitable reagentsBackground Nitrogen monoxide has a very limited solubility in water.
