Question
A solution of colourless salt H on boiling with excess NaOH produces a non-flammable gas. The gas evolution ceases after sometime. Upon addition of Zn dust to the same solution, the gas evolution restarts. The colourless salt (s) H is(are)
Options
A.NH4NO3
B.NH4NO2
C.NH4Cl
D.(NH4)2SO4
Solution
NH4NO3 + NaOH → NH3 + NaNO3 + H2O
7NaOH + NaNO3 + 4Zn → 4Na2ZnO2 + NH3 + 2H2O
NH4NO2 + NaOH → NaNO2 + NH3 + H2O
3Zn + 5NaOH + NaNO2 → 3Na2ZnO2 + NH3 + H2O
7NaOH + NaNO3 + 4Zn → 4Na2ZnO2 + NH3 + 2H2O
NH4NO2 + NaOH → NaNO2 + NH3 + H2O
3Zn + 5NaOH + NaNO2 → 3Na2ZnO2 + NH3 + H2O
