A student adds aqueous hydrogen peroxide to acidified potassium iodide solution.
A brown colour appears and bubbles are seen.
In this reaction, hydrogen peroxide is acting as
A brown colour appears and bubbles are seen.
In this reaction, hydrogen peroxide is acting as
- an oxidising agent because it oxidises iodide ions to iodine.
- an oxidising agent because it is oxidised to oxygen gas.
- a reducing agent because it reduces iodide ions to iodine.
- a reducing agent because it gains electrons from iodide ions.
