Question

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

Answer 1

Hey mate,, here is ur ans..

Chemical test to distinguish between CO and H₂ are as follow:

• If we oxidize CO in excess of O₂ ,it will give CO₂ gas and passing though lime water [Ca(OH)₂], it turns it milky.

                      CO  +  O₂ →  CO₂

            CO₂ +  Ca(OH)₂ →  CaCO₃  + H₂O

But hydrogen does not give this test.

• Another test is to treat vegetable oils with hydrogen gas to give solid fat, but CO does not give this reaction.

                      Vegetable oil  +  H₂ → Fat

                  Vegetable oil  +  CO → No reaction
