Canned Heat
Liquid ethanol is poured into a saturated calcium acetate solution and a solid gel is formed. The gel burns like canned heat (Sterno™).
applications of chemistry
Ferrimagnetism - Part 1 of 2 - Hematite and Magnetite
Hematite and magnetite are formed from iron(II) and iron(III) solutions.
Ferrimagnetism - Part 2 of 2 - Testing for Magnetism
Hematite and magnetite samples are tested for magnetism.
Ring Strain - Historical Note
This is a simulation of how the reaction of iodine with α-pinene was used as a form of antisepsis.
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.
