We started off doing 4 practicals (3 pracs and a demo)
We then talked about the observations from the practical. Colour changes are important in redox chemistry as they enable us to determine what species have reacted and changed. You need to link the colour changes observed to the species present
Then we then moved on to half equations.
Then we then moved on to half equations.
The rules are also on page 72 of your Scipad or you can see a worked example with the rules step by step here. You need to use both changes in oxidation number AND half equations linked to colour changes to justify your answers in order to get excellence.
Tomorrow we will continue practicing 1/2 equations and oxidation numbers
