Crikey. I'll be glad of a rest on Friday when I'm back in. Anyway, we've nearly finished the first chunk of transition metal chemistry. We've covered transition metal complexes and their uses, catalysis and the variable oxidation state of these metals.
We also need to know about transition metals and colour so you will need to read through pages 219-222 of your A2 text book and make notes on 'the origin of colour' and 'using colour to determine concentration'. We will be doing some practical work to reinforce these ideas on Friday and during the following week.
Also, you will need to ensure that your homework (the 5 past paper sheets I gave you last week) is up to date for Friday.
Finally, seeing as we are coming to the end of a big dollop of transition metal stuff it would make sense to have a small test before Easter, so you might want to make sure you understand everything we've done so far. Use the questions on pages 240 and 241 to check your level of understanding (answers are in the back of the book).
