The Combustion of Methane

In this classic demonstration, from the Royal Society of Chemistry, a coffee can is filled with methane and fitted with a glass chimney. The gas is burnt and when it reaches the can it explodes and the lid is blown off.

Equilibria Involving Carbon Dioxide and their Effect on the Acidity of Soda Water

In this classic demonstration, from the Royal Society of Chemistry, soda water containing indicator is placed in a syringe. With one end sealed, the pressure is reduced by pulling back on the syringe. The carbon dioxide is seen outgassing from the soda water and the solution becomes less acidic.

The Tubeless Siphon

In this classic demonstration, from the Royal Society of Chemistry, a viscous liquid of polyethylene oxide in propan-2-ol (isopropanol) is poured into a second beaker. On returning the first beaker to the upright position, the liquid continues to siphon by climbing up the side of the beaker and over the rim.

‘Magic’ Writing

In this classic demonstration, from the Royal Society of Chemistry, messages are written on filter paper using colourless dilute solutions, including those of several transition metals. When the filter papers are sprayed with other solutions, the messages appear in a variety of colours.

The Photochemical Reactions of Chlorine with Hydrogen and with Methane

In this classic demonstration, from the Royal Society of Chemistry, shining a strong light onto a cored bottle of chlorine and hydrogen causes a rapid photochemical reaction and the bottle explodes. A less rapid reaction occurs with methane and chlorine.

Dyeing – Three Colours from the Same Dye-bath

In this classic demonstration, from the Royal Society of Chemistry, three different materials such as wool, silk and nylon are placed in a dye bath containing blue, red and yellow dye. The materials emerge different colours due to the interactions of the materials and the dyes.

Making Silicon and Silanes from Sand

In this classic demonstration, from the Royal Society of Chemistry, magnesium and sand are heated together producing silicon in a very exothermic reaction. Acid is used to remove unreacted magnesium and magnesium oxide.

The Ammonium Dichromate ‘Volcano’

In this classic demonstration, from the Royal Society of Chemistry, a conical pile of orange ammonium dichromate is ignited. This produces a large volume of green chromium (III) oxide and steam.

The Enthalpy and Entropy Changes on the Vaporisation of Water

In this classic demonstration, from the Royal Society of Chemistry, a kettle of known power is kept boiling for two minutes, the change in mass of the water can be used to calculate the enthalpy and entropy changes.

Estimating the Concentration of Domestic Bleach

In this classic demonstration, from the Royal Society of Chemistry, an excess of hydrogen peroxide is added to household bleach and the volume of oxygen evolved is measured. Using the ideal gas equation the concentration of sodium chlorate in the bleach can be determined.
