The Density of Carbon Dioxide

In this classic demonstration, from the Royal Society of Chemistry, carbon dioxide is poured onto a candle flame in a beaker and the flame is extinguished. The candle will not relight until the carbon dioxide is poured out of the beaker.

Catalysts for the Decomposition of Hydrogen Peroxide

In this classic demonstration, from the Royal Society of Chemistry, the catalysing power of different catalysts is measured by adding them to washing up liquid and measuring the rate of foam production when hydrogen peroxide is added. Chemical and natural catalysts are used in this demonstration.

Making Nylon – the ‘Nylon Rope Trick’

In this classic demonstration, from the Royal Society of Chemistry, a solution of decanedioyl dichloride is floated on a solution of diaminohexane. At the interface of the two liquids, the condensation polymer nylon forms and it can be carefully removed as a long rope.

The Greenhouse Effect – 1

In this classic demonstration, from the Royal Society of Chemistry, thermometers are clamped near a photoflood bulb. One is clamped in air, one in a plastic drinks bottle and the third is clamped in a drinks bottle painted with matt black paint. The steady state temperature of the thermometers is measured.

The Greenhouse Effect – 2

In this classic demonstration, from the Royal Society of Chemistry, two beakers which contain a thermometer and a lead foil disc are placed below a photoflood bulb. Once the temperature has stabilised, one beaker is flooded with carbon dioxide.

The Preparation of Nitrogen Monoxide and its Reaction with Oxygen

In this classic demonstration, from the Royal Society of Chemistry, nitrogen monoxide is prepared by reacting iron (II) sulphate with sodium nitrate in acidic solution, reacting the nitrogen monoxide produced with oxygen produces brown nitrogen dioxide. This experiment can be carried out using equal volumes of...

Reactions of the Alkali Metals

In this classic demonstration, from the Royal Society of Chemistry, the reactions of lithium, sodium and potassium are demonstrated by reacting with water and chlorine. The physical properties of these metals are also demonstrated.

Sulphur

In this classic demonstration, from the Royal Society of Chemistry, sulphur is heated to show it’s various forms which include: sulphur rings, long sulphur chains, short sulphur chains. Cooling the sulphur forms plastic sulphur whilst dissolving it in toluene, and then evaporating the solvent, forms rhombic...

The Thermit Reaction

In this classic demonstration, from the Royal Society of Chemistry, a spectacular reaction to produce molten iron is carried out by reacting iron (II) oxide and aluminium powder together and igniting with a magnesium splint.

The Reaction of Magnesium with Steam

In this classic demonstration, from the Royal Society of Chemistry, burning magnesium is plunged into steam above boiling water. There are two methods given - in one the hydrogen burns at the mouth of the flask, in the second it is collected.
