Question

give chemical test to identify ammonia

Answer 1

Add aqueous sodium hydroxide to the solid, or solution, under test and warm the mixture. Result: If ammonium ions are present then a pungent-smelling gas is produced. The gas produced turns damp red litmus paper blue. It is ammonia, NH3

Answer 2

Experiment :

Aim : To identify ammonia .

Materials :

• beaker containing HCl .

• a glass rod .

Procedure.

• Dip the glass rod in HCl .

• Bring the glass rod near ammonia.

Observation :

• If you see that the glass rod shows dense white fumes , then it is ammonia .

• This way we can test the ammonia.

Conclusion

Thus we learnt the test for ammonia.

Reaction :

NH₃ + HCl =====> NH₄Cl
