Question

Describe one chemical test applied to the following gases which would enable you to distinguish between them carbon dioxide and hydrogen chloride gas

Answer 1

When carban dioxidi reacts with limewater it turns limewater[Ca(OH)2] milky due to the formation of insoluble calcium carbonate(CaCO3).


Ammonia has a sharp smell .It turns red litmus blue.It also forms a white smoke of Ammonia chloride. When concentrated hydrochloride gas is near it.

Answer 2

Experiment :

Aim : To distinguish HCl and CO₂ .

Materials :

• beaker containing ammonia.

• a glass rod .

Procedure.

• Dip the glass rod in ammonia .

• Bring the glass rod near both.

Observation :

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

• This way we can test the hydrogen chloride.

• The other one is carbon-dioxide.

Conclusion

Thus we learnt the test for hydrogen chloride.

Reaction :

NH₃ + HCl =====> NH₄Cl
