Learn the basics about Displacement reactions and reactions in solutions. What are displacement reactions? and what they in solutions? Find out more in this video! This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind The
Chemists always distinguish between the macroscopic and microscopic level. What does that mean? In the experiment zinc reacts with sulphur, this level is attempted to be demonstrated. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The three types of a chemical reaction (analysis, synthesis and conversion) are only presented theoretically! An application and chemical experiments for this take place in the attendance phase at school! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done b
Learn the basics about the exchange of oxygen in oxidation-reduction reactions (REDOX) when learning about chemical reactions. In a chemical reaction, oxidation is oxygen GAIN and reduction is oxygen LOSS. A good example of oxidation is a combustion reaction. Hydrogen is a clean fuel that works by

Salts are formed from the reaction of their elements. It is explained how the electron release, electron uptake and the overall reaction are to be formulated. In order to be able to formulate the redox reactions later, this type of reaction is very important! Original: "Wolfgang Dukorn" Original:
How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
Detection of halide ions (chloride, bromide and iodide ions) with silver nitrate is explained. This type of reaction is also called precipitation reactions. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The screencast shows how to formulate reaction equations in the chemical formula language. The law of conservation of mass is fundamental and is evident both at the particle level and in the reaction equation. Afterwards it is necessary to practice a lot! Original: "Wolfgang Dukorn" Original: Germ
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
Quick and short explanation of the saponification reaction, first in general and then with a concrete example. Only the hydrolysis of a fat molecule is discussed and no mechanism is explained. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha
Using the example of the reaction between water and oxygen, the essential statements of a chemical reaction are described. What quantities of substances must be used? What does this mean for their masses? This is an introduction to stoichiometric calculations! Original: "Wolfgang Dukorn" Original:
