The oxidation states of iodine in HIO4 , H3 IO5 and H5 IO6 are respectively
(a) + 1, + 3, + 7
(b) + 7, + 7, + 3
(c) + 7, + 7, + 7
(d) + 7, + 5, + 3
Correct option: (c) + 7, + 7, + 7
Explanation:
Calculating the oxidation states of I, we get
H5 IO6 ; 5 + x – 12 = 0 or x = +7
H3 IO5 ; 3 + x – 10 = 0 or x = +7
HIO4 ; 1 + x – 8 = 0 or x = +7
Thus, the correct answer is + 7, +7, +7
