    The reaction of slaked lime with \[C{{l}_{2}}\] gas gives:

    A)  only \[Ca{{(OCl)}_{2}}\]

    B)  only \[CaC{{l}_{2}}\]

    C)  a mixture of\[Ca{{(OCl)}_{2}},Ca{{(OH)}_{2}},CaC{{l}_{2}}\]and\[{{H}_{2}}O\]

    D)  quicklime

    E)  baryta water

    Correct Answer: A

    Solution :

    The reaction of slaked lime with\[C{{l}_{2}}\]give bleaching powder\[(CaOC{{l}_{2}})\]. \[\underset{slaked\text{ }lime}{\mathop{Ca{{(OH)}_{2}}}}\,+C{{l}_{2}}\xrightarrow{{}}\underset{bleaching\text{ }powder}{\mathop{CaOC{{l}_{2}}}}\,+{{H}_{2}}O\]
