Series: Chemistry
Acids and Bases
We come into contact with a variety of different acids and bases every day. In this video, students will learn about some of the common acids and bases that they use and interact with on a daily basis.
Air
Objective:
To learn about air.
Learning outcomes - students will be able to:
1. Define air and its composition
2. Discuss the percentage of different gases present in air
3. Explain that air occupies space
Application of Radioisotopes
Radioisotopes are unstable atoms that emit radiation, and decay to form stable atoms. Some of their uses are as nuclear fuel and as tracers in medicinal fields.
Applications of Colloids in Everyday Life
This video defines colloids and explains their importance in pharmaceutical preparations.
Applying the Concepts
The programme covers Le Chatelier's principle, the equilibrium law, calculating K. It examines how K changes when the temperature of exothermic and endothermic reactions changes, with a focus on sulphuric acid manufacture.
Avogadro's Law
Avogadro’s Law describes the relationship between the volume of a gas and the number of molecules in it, at constant temperature and pressure. Students will learn how to prove the law in this video.
Caustic Soda
Sodium hydroxide is produced by the electrolysis of sodium chloride solution. During electrolysis, hydrogen gas evolves at the cathode and chlorine gas evolves at the anode.
Changes in States of Matter
Objective:
To learn about the changes in the states of matter.
Learning outcomes - students will be able to:
1. Identify the three states of matter;
2. Understand how ice, water, and water vapour are formed.
