Acids, Alkalis and Bases: An Introduction (RLO) | This RLO gently introduces students to the pH scale, the concept of indirect measurement and molecule dissocation into ions. It explains why pure water is netural (ph 7), why acids have a low pH value, and why alkalis and bases have a high pH value. |
Acids, Alkalis and Bases: Further Application (RLO) | This RLO explains further the concept of acid, base and alkali dissociation in water and the effect this has on a solution's pH. This RLO also explains the terms buffers, denaturation, neutralisation and the formation of salt. |
Atomic Bonding (RLO) | This RLO examines ionic, covalent and mixed bonding in atoms. |
Atomic Structure (RLO) | Introducing basic atomic structure, properties, chemistry and notation. |
Elements that make up the human body (RLO) | Introducing the periodic table of elements, and identifying the major elements involved in the human body and their roles. |
A closer look at water | A short but instructive animation illustrating the polarity of water and hydrogen bonding. Produced by Northland Community & Technical College, Minnesota, USA. |
