    The oxidation states of iodine in \[HI{{O}_{4}},\]\[{{H}_{3}}I{{O}_{5}}\] and \[{{H}_{5}}I{{O}_{6}}\] are respectively

    A) +1, +3, +7      

    B)        +7, +7, +3

    C) +7, +7, +7      

    D)        +7, +5, +3

    Correct Answer: C

    Solution :

    [c] Calculating the oxidation states of I, we get \[{{H}_{5}}I{{O}_{6}};\]\[5+x-12=0\]or \[x=+7\] \[{{H}_{3}}I{{O}_{5}};\]\[3+x-10=0\]or \[x=+7\] \[HI{{O}_{5}};\]\[1+x-8=0\]or \[x=+7\] Thus, the correct answer is \[+7,\]\[+7,\]\[+7\]
