OCR AS Chemistry Evaluation Coursework

hey guys! we have our evaluative coursework tomorrow, but our teachers haven't prepared us for it. do u guys have any tips or any websites I can use to revise? the questions about alternative methods/equipment are particularly hard since we haven't used much equipment other than those for titration :frown:

any help would be appreciated. thank you :smile:

Did your teachers give you the Practical Skills handbook?

Pages 28-33 are seriously useful/important for the evaluative paper.

Wait did you have it yesterday? If not

Basically there is nothing on mass spec

You need to know limitations of infrared spec
You need to know how to calculate percentage error for burette volumetric flask and pipettes
You need to know how the mean titre will change if you make mistakes in your titration
You need to be able to draw e/z isomers
Remember the reactions of alcohols
Remember the test for unsaturation
And you need to be able to write equations for compound with more than one functional group reacting with metals

Hi has anyone completed the evaluation about calculations of volumes and moles well the title is something similar can't really remember. If you have any advice on what to revise. I have revised calculations for moles and titration can't think of anything else I have always scored no higher than 8 on evaluations. An
