    On passing IF electricity in acid solution, the oxygen liberates

    A)  \[11.2\,d{{m}^{3}}\]        

    B)  \[5.6\,d{{m}^{3}}\]

    C)  \[22.4\text{ }d{{m}^{3}}\]        

    D)  \[1.0\text{ }d{{m}^{3}}\]

    Correct Answer: B

    Solution :

     Weight of \[{{O}_{2}}=\frac{E}{F}\times Q\] \[=\frac{8}{1F}\times F=8g\] Volume of\[8\,g\,{{\text{O}}_{2}}\]on NTP\[=22.4\times \frac{8}{32}d{{m}^{3}}\] \[=5.6\text{ }d{{m}^{3}}\]
