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

टीपा लिहा

उत्तर

\[\ce{Carbon monoxide 2Co + O2 ->\underset{\text{Turns lime water milky}}{2CO}}\]

\[\ce{2H2 + O2->[2000°C] 2H2O}\] 
does not turn lime water milky. It is neutral.
Co dissolves in Ammonical cuprous chloride when passed through it
CO + CuCl + 2H2O → CuCl.CO.2H2
