Question

For a particular redox reaction ClO2– is oxidized to ClO4– and Fe3 is reduced to Fe2 . Complete and balance the equation for this reaction in basic solution. Phases are optional.

Answer 1

The complete and balance the equation for the reaction, in basic solution, is written below:

$4OH^{-}(aq.)+ClO2^{-}(aq.)+4Fe^{3+}(aq.)-\ \textgreater \ ClO4^{-}(aq.)+4Fe^{2+}(aq.) + 2H_{2}O(l)$

In must be noted that, a redox reaction is said to be balance, when both charge and mass is balanced on both reactant and product side. In present case, net charge on reactant side is +7, which is same as product side. Hence, the reaction is both mass and charge balanced. 

Answer 2

For a particular redox reaction ClO2– is oxidized to ClO4– and Fe3 is reduced to Fe2 . The balanced redox reaction is expressed as:


4OH-+ClO2- + 4Fe^3+ ---> ClO4- + 4Fe2+ + 2H2O

Hope this answers the question. Have a nice day.
