        Which of the following is used as a test for detecting the presence of carbon monoxide?

    A)  Reduction of metallic oxides to metals

    B)  Reduction of water to hydrogen

    C)  Reduction of\[PdC{{l}_{2}}\]to\[Pd\](Black)

    D)  All of the above

    Correct Answer: C

    Solution :

                    Carbon mono oxide easily oxidise to\[C{{O}_{2}}\]. It act as a reducing agent and reduces metallic oxide to metals. Water to\[{{H}_{2}}\]and\[PdC{{l}_{2}}\]to\[Pd\](black). But the reduction of\[PdC{{l}_{2}}\]to\[Pd\] (black) is used as a test for detecting the presence of CO.
