    When IF of electricity is passed through acidulated water,\[{{O}_{2}}\]evolved is:

    A)  \[11.2\text{ }d{{m}^{3}}\]       

    B)  \[5.6\text{ }d{{m}^{3}}\]

    C)  \[22.4\text{ }d{{m}^{3}}\]

    D)  \[1.0\text{ }d{{m}^{3}}\]

    Correct Answer: B

    Solution :

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