HIO3 =

In these reactions involving iodine (I), determine whether iodine is oxidized or reduced.Iodine (I) and hydrogen sulfide (H2S) combine to form hydrogen iodide and sulfur (S8).8I2 + 8H2S 16HI + S8 Iodine is

Iodine (I2) and aluminum (Al) combine to form aluminum iodide (AlI3). 3I2 + 2Al 2AlI3 Iodine is

Hydrogen iodide (2HI) and chlorine gas (Cl2) combine to form hydrogen chloride (2HCl) and iodine (I2). 2HI + Cl2 ® 2HCl + I2 Iodine is
