Ring Strain - Historical Note
This is a simulation of how the reaction of iodine with α-pinene was used as a form of antisepsis.
applications of chemistry
Ferrofluid - Demonstration
Spikes in aqueous ferrofluid are formed in response to a magnet.
Reaction of magnesium with carbon dioxide
The reaction of magnesium with carbon dioxide (dry ice) is demonstrated. Despite the absence of air, the magnesium continues to glow.
Oxidation and reduction of copper
A piece of copper metal is heated in a flame and oxidized to black copper oxide by air. The oxidized copper is reduced when placed in a hydrogen atmosphere. When removed from the hydrogen atmosphere, the metal is again oxidized.
