Demonstration Videos
The RSC commissioned a series of video demonstrations providing guidance for some fundamental, and some very exciting, reactions.
Accompanying notes from Classic Chemistry Demonstrations are provided for the demonstration videos.
Post-16. Demonstrating the Tollens' test for aldehydes and reducing sugars
14-18 age group. This demonstration shows that the energy of a chemical reaction can be given out as light as well as heat
Pre-16. Petrochemicals/crude oil/industrial chemistry/hydrocarbons, alcohols
Electrolysis of Molten Lead Bromide
Pre-16. A demonstration to show the conduction of the molten electrolyte and that bromine is produced
Making silicon and silanes from sand
Pre or post-16. The reactions of group IV elements
Electrolysis of Molten Zinc Chloride
This demonstration shows that an ionic salt conducts electricity when molten but not when solid
This demonstration touches on a number of areas of chemistry - density of gases, diffusion, solubility of gases, sublimation and combustion
A simple demonstration of catalysis also introducing the idea of an activated complex and to allow discussion of the mechanism of catalysis
This demonstration will probably be done for entertainment/general interest
Burning milk powder - the effect of surface area on reaction rate
Pre-16. Rates of reaction
Catalysts for the decomposition of hydrogen peroxide
Pre-16. Reaction rates, catalysis, enzymes
Determination of relative molecular masses by weighing gases
Post-16. Gases, relative molecular masses
Reactions of the alkali metals
Pre-16. Group I metals (alkali metals), the Periodic Table
Gases - solubility and acidity/alkalinity
Combustion, energy changes in reactions, balancing equations, Avogadro's law and general interest
Combustion, but this is essentially a 'fun' demonstration
Pre-16. Formula determination, extraction of metals
Turning 'red wine' into 'water'
This is a fun demonstration suitable for an open day
Zinc-plating copper and the formation of brass - 'turning copper into 'silver' and 'gold''
Electrochemistry, electroplating, alloys
