Iodine is the only halogen that occurs in a positive oxidation state, in NaIO3
Chapter 22, Problem 22.36(choose chapter or problem)
Iodine is the only halogen that occurs in a positive oxidation state, in NaIO3 impurities within Chile saltpeter, NaNO3. (a) Is this mode of occurrence consistent with iodines location in the periodic table? Explain. (b) In the production of I2, IO3 2 reacts with HSO3 2: IO3 2(aq) 1 HSO3 2(aq) - HSO4 2(aq) 1 SO4 22(aq) 1 H2O(l) 1 I2(s) [unbalanced] Identify the oxidizing and reducing agents. (c) If 0.78 mol % of an NaNO3 deposit is NaIO3, how much I2 (in g) can be obtained from 1.000 ton (2000. lb) of the deposit?
