Arrange the following in order from most oxidized to least oxidized.

Question

Quizplus · Accepted Answer

To determine the order from most oxidized to least oxidized, we need to consider the oxidation states of each species. The more positive the oxidation state, the more oxidized the species is.

Iodine has an oxidation state of -1 in I-, 0 in I2, and +5 in IO3-. Therefore, III (IO3-) is the most oxidized, followed by II (I2), and then I (I-).

So, the correct order from most to least oxidized is III > II > I, which corresponds to choice B.
