Produce oxygen by heating potassium manganate(VII), then identify it with a glowing splint
Potassium manganate(VII) produces oxygen when heated. In this experiment oxygen is produced and identified with a glowing splint.
This practical is part of our Classic chemistry experiments collection.
He is most famous for his discovery of oxygen (O), but he also discovered laughing gas, was the first to carbonate water and was a pioneer of research into electricity.
