    The oxidation state of sulphur in sodium tetrathionate \[\text{(N}{{\text{a}}_{2}}{{\text{S}}_{4}}{{\text{O}}_{6}}\text{)}\]is

    A)  2               

    B)  0

    C)  2.5             

    D)  3.5

    Correct Answer: C

    Solution :

     Let the oxidation state of sulphur in\[\text{N}{{\text{a}}_{\text{2}}}{{\text{S}}_{\text{4}}}{{\text{O}}_{\text{6}}}\] is\[x.\] \[N{{a}_{2}}{{S}_{4}}{{O}_{6}}\] \[1\times 2+4\times x+(-2)\times 6=0\] \[2+4x-12=0\] \[4x-10=0\] \[4x=10\] \[x=\frac{10}{4}=2.5\]
