Chemistry Demonstrations for Primary and Secondary 

Use these 10 spectacular reactions to excite your science classes.

1	Sodium and Water – the spectacular reaction between sodium metal and water both on a laboratory scale and on a much larger scale.
2	Oxides of Nitrogen –  the production of nitric oxide and nitrogen dioxide from the reaction between copper metal and nitric acid.
3	Zinc and Sulfur – the production of zinc sulfide from the reaction between powdered zinc metal and sulfur
4	Copper Sulfate and Ammonia – the formation of the precipitate copper(II) hydroxide and the complex ion Cu(NH3)4 2+
5	Ammonia Fountain – the incredible solubility of ammonia gas in water and the formation of the basic solution containing NH3(aq)
6	Aluminium and Iron Oxide – the amazing thermite reaction producing molten iron from the reaction between powdered aluminium metal and iron(III) oxide.
7	Ammonium Dichromate Volcano – the fascinating production of green chromic oxide from the decomposition of ammonium dichromate.
8	The Blue Bottle – glucose, sodium hydroxide and methylene blue gives the mysterious solution which oscillates between blue and colourless.
9	Sugar and Sulfuric Acid – a spectacular demonstration of the dehydrating power of concentrated sulfuric acid.
10	Lemon Power – an electric current from an ordinary lemon plus some zinc and copper metal and connecting wires.
