The Electrolysis of Water – Exploding Bubbles of Oxygen and Hydrogen

In this classic demonstration, from the Royal Society of Chemistry, platinum electrodes are used to electrolyse a dilute solution of sodium sulphate containing universal indicator and a little washing up liquid. The evolving gasses can be used to create bubbles which will explode.

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.

The Reactions of Chlorine, Bromine and Iodine with Iron

In this classic demonstration, from the Royal Society of Chemistry, iron wool is heated in the presence of chlorine gas and the vapours of iodine and bromine. A vigorous exothermic reaction occurs and iron (III) halides are produced. The order of reactivity in group 7 can be determined from this demonstration....

Following the Reaction of Sodium Thiosulphate and Acid Using a Colorimeter

In this classic demonstration, from the Royal Society of Chemistry, the reaction between sodium thiosulphate and acid which produces solid sulphur is monitored using a colorimeter.

The resource provides a list of apparatus and chemicals needed for the experiment, together with teaching tips.

The Fountain Experiment

In this classic demonstration, from the Royal Society of Chemistry, a large round bottomed flask containing a soluble gas such as ammonia is clamped upside down and connected to a trough of water containing indicator by a glass tube. When a small amount of water is injected to the flask, the gas dissolves creating...

The Preparation and Properties of Nitrogen(I) Oxide

In this classic demonstration, from the Royal Society of Chemistry, nitrogen (I) oxide is prepared by reacting sodium nitrate and ammonium sulphate. The nitrogen oxide is shown to re-light a glowing splint and be partially soluble in water; heating the gas with copper leaves nitrogen gas.
