Chlorate(I) ions, ClO−\text{ClO}^-ClO−, react with iodide ions, I−\text{I}^-I−, in acidic conditions to form chloride ions, iodine, and water:
ClO−(aq)+2I−(aq)+2H+(aq)→Cl−(aq)+I2(aq)+H2O(l) \text{ClO}^-\text{(aq)} + 2\text{I}^-\text{(aq)} + 2\text{H}^+\text{(aq)} \rightarrow \text{Cl}^-\text{(aq)} + \text{I}_2\text{(aq)} + \text{H}_2\text{O(l)} ClO−(aq)+2I−(aq)+2H+(aq)→Cl−(aq)+I2(aq)+H2O(l)Which species is the reducing agent in this reaction?
ClO−(aq)\text{ClO}^-\text{(aq)}ClO−(aq)
I−(aq)\text{I}^-\text{(aq)}I−(aq)
H+(aq)\text{H}^+\text{(aq)}H+(aq)
I2(aq)\text{I}_2\text{(aq)}I2(aq)
