The oxidation states of iodine in HIO₄, H₃IO₅ and H₅IO₆ respectively, are
A.+1, +3, +7
B.+7, +7, +3
C.+7, +7, +7✓ Correct
D.+7, +5, +3
Explanation
Let us consider the oxidation states of iodine for each given compound as x 4 3 5 5 6 HIO 1+x-8=0, x =+7 H IO 3+x-10=0, x = +7 H IO 5+x-12= +7, x = +7 → → → Therefore, option (c) is correct.
