Answer:
In the electrolysis of potassium iodide solution, scientist found hydrogen gas being collected at the cathode. The potassium iodide solution means KI+H2 O.
After the electrolysis of the solution the hydrogen comes from water (H2 O). The potassium iodide solution contains the water molecules i.e. iodide ions (I–) and potassium ions (K+).The substance which is formed at cathode is reduction product.
