Question

When ammonia salt is warmed with sodium hydroxide solutionammonia gas is evolved state 3ways which u can idenrify it?

Answer 1

The gas ammonia is released

It has a formula NH3NH3

This is a decomposition reaction of ammonium compounds

NH4Cl+NaOH→NaCl+H2O+NH3NH4Cl+NaOH→NaCl+H2O+NH3

If we break down this reactions to check what happens to the ions present then see:

NH+4+Cl−→Na++Cl−+H2O+NH3NH4++Cl−→Na++Cl−+H2O+NH3

NH3+H++Cl−→Na++Cl−+H2O+NH3NH3+H++Cl−→Na++Cl−+H2O+NH3

Here, we can see that ammonia molecule breaks off from the ammonium ion and leaving an H+H+ and Cl−Cl−. So these ion react with the NaOH as HCl.

So leaving the ammonia produced, the rest of the reaction is a neutralization reaction. Thus the salt sodium chloride along with water is made.
