Competition for oxygen


This experiment involves the reaction of a metal with the oxide of another metal. When reactions like these occur, the two metals compete for the oxygen. The more reactive metal finishes up with the oxygen (as a metal oxide). If the more reactive metal starts as the oxide then no reaction takes place.


This experiment is one of a collection of 100 experiments in a book called Classic Chemistry Experiments. You can buy a copy via the Royal Society of Chemistry online shop for £27.50.
