Chemistry Captured
Mae'r cynnwys hwn ar gael yn Saesneg yn unig.
Chemistry Captures is a valuable e-learning resource of high-quality videos of chemical reactions that would otherwise be difficult to demonstrate in schools.
Here are a series of video clips produced by our Professor Peter Edwards and Mr Peter Hollamby in partnership with the Royal Society of Chemistry (RSC) and the Gatsby Science Enhancement Programme.
The video clips were published on two DVDs, which were made available to all schools in the UK.
Preparation of Oxygen and Chlorine
Video produced by Peter Hollamby and Peter Edwards
Physical states of the Halogens
Video produced by Peter Hollamby and Peter Edwards
Reactions with the Halogens
Reactions of the Halogens with the Elements of Period III of the Periodic Table.
Reactions with Oxygen
Reactions of Oxygen (and air) with the Elements of Period III of the Periodic Table and some other Group I Metals.
Hydrolysis of the Chlorides of Period III Elements
Action of water on the chlorides of elements of Period III of the Periodic Table.
Thermal Decomposition
Thermal decomposition of Ammonium Dichromate VI
Endothermic Reaction
An endothermic reaction: Barium Hydroxide and Ammonium Thiocyanate
See also, Cobalt Chloride and Thionyl Chloride on our YouTube channel
Catalytic Oxidation of Ammonia
This reaction illustrates the formation of nitric oxide from ammonia gas using a platinum catalyst.
See also, the catalytic oxidation of hydrogen on our YouTube channel.
Photochlorination
Reaction between hydrogen and chlorine.
See the reaction between chlorine and methane on our YouTube channel
Effect of temperature on equilibrium
Effect of temperature on the equilibrium between dinitrogen tetroxide and nitrogen dioxide
Rusting Steel Wool
This Time-lapse video recording illustrates how quickly rust can form and how a simple piece of apparatus can be used to determine the percentage of oxygen in the air.
Reaction between methane and chlorine
A REDOX reaction between methane and chlorine gases, producing carbon 'soot' and hydrogen chloride vapour.
The Barking Dog
This famous exothermic reaction takes place when a mixture of carbon disulfide with nitrous oxide or alternatively with nitric oxide is ignited. The sound of the explosion in the tube is similar to that of a barking dog.
Displacement of Silver
This displacement reaction has been recorded by time-lapse photography. The sequence that follows was filmed over a 30 minute period.
Formation of ammonium chloride
In this video cotton wool is soaked with a little concentrated ammonia solution. A second wad is similarly treated with concentrated hydrochloric acid solution.
Formation of Plastic Sulfur
Plastic sulfur is not a true Allotrope of sulfur but this unusual form of the element can be made quite easily by melting it and then cooling the liquid rapidly by pouring it into cold water.
Electrode Potentials Introduction
The hydrogen electrode and the measurement of some electrode potentials.
