Chemistry · Secondary 4 · Medium · Oxidising and reducing agents
In an experiment, aqueous hydrogen peroxide is added to acidified potassium iodide solution. The brown colour of iodine appears and bubbles of gas are seen. In this reaction, hydrogen peroxide is acting mainly as
- an oxidising agent, because iodide ions lose electrons.
- an oxidising agent, because iodide ions gain electrons.
- a reducing agent, because iodide ions lose electrons.
- a reducing agent, because iodide ions gain electrons.
