To all those who are suffering the wrath of OCR Salters Chemistry, I bring to you, a thread dedicated to helping those in need.
On this page we will share online resources, attachments and give general advice and help to each other in order to create the largest OCR Salters Study Resource for current and future A-Level Students.
As a welcome gift, I give to you: http://4college.co.uk a website for OCR Salters Revision Notes and an attached revision guide for Elements of the Sea. More will follow...
CGP have provided a revision and practice guide for the OCR Salters course. I recently purchased one and after a thorough readthrough, I must admit that it is quite brilliant!
Word of warning: I wouldn't rely on this book entirely. Use Chemical Ideas for some parts.
For those of you who like to revise from Chemical Ideas, you've probably already downloaded the mark scheme from the Internet.
However, this is a more updated and accurate mark scheme where the questions correspond to the answers and all exercises are covered. Check it out here: http://boswellsgmt.wikispaces.com/CHEMICAL+IDEAS
Cannot get my head around Emission and absorption spectrums.
Just remember that...
-Electrons absorb energy and raised to higher electronic energy levels (1) -Electrons drop back to ground state, losing energy as light (1) -Energy levels quantized (1); drops between specific energy levels are given by Planck's equation, E = hv (1) -Each set represent drops to different lower electronic energy levels (1) + include named example such as Lyman/Balmer series.
-Electrons absorb energy and raised to higher electronic energy levels -This produces lines that form an absorption spectra consisting of black lines on a coloured background -Energy levels quantized; differences between specific energy levels are given by Planck's equation, E = hv -Each set represent rises to different higher electronic energy levels
