Ammonium sulphate is heated with NaOH and the gas liberated is bubbled into methyl orange solution
Dear student,
When ammonium sulphate is heated with sodium hydroxide, sodium sulphate is formed with the liberation of Ammonia gas and water vapor. The reaction is as follows:
(NH4)2SO4(s) + NaOH(s) + heat > Na2SO4(s) + NH3(g) + H2O(g)
Since, upon addition of Ammonia in water forms ammonium hydroxide, hence when ammonia gas is bubbled through methyl orange solution, the colour changes from orange to yellow.
NH3(g) + H2O(l) > NH4OH(aq) (basic in nature)
