    What amount of \[C{{l}_{2}}\]gas is liberated at an 1 ampere current is passed for 30 minute from NaCl solution?

    A)  0.44 moles                 

    B)  0.24 moles

    C)  0.66 g                        

    D)  0.21 g

    Correct Answer: C

    Solution :

    \[2C{{l}^{-}}\to C{{l}_{2}}+2{{e}^{-}}\](At anode) \[\text{1}\,\text{mole}\,2\times 96500\,\,\text{coulomb}\] \[Q=i.t=1\times 30\times 60\] = 1800 coulomb Hence, the amount of chloride liberated by passing 1800 coulomb of electric charge \[=\frac{1\times 1800\times 71}{2\times 96500}\] Hence, the correct option is [c].
