3B: LABORATORY CHEMISTRY
a) recognise the results of reactions of compounds specifically mentioned in Units 1 and 2 of the specification and the results of tests for simple ions: carbonate, hydrogencarbonate, sulphate (VI), sulphite, chloride, bromide, iodide, nitrate, ammonium, lithium, sodium, potassium, magnesium, calcium, strontium and barium
b) recognise the chemical tests for simple gases, to include hydrogen, oxygen, carbon dioxide, ammonia, chlorine, nitrogen dioxide and sulphur dioxide
c) describe the techniques used in volumetric analysis and enthalpy change measurements
d) describe the techniques used in simple organic preparations such as distillation and heating under reflux
e) recall and interpret details of the chemistry of the elements and compounds listed in Units 1 and 2 of this specification
• this includes the chemistry of Groups 1, 2 and 7 and the chemistry associated with the organic compounds listed in topic 2.2
f) interpret quantitative and qualitative results
g) devise and plan simple experiments based on the chemistry and techniques summarised in a to e above
h) evaluate error in quantitative experiments
• see Appendix I for material available to assist centres in teaching this area
i) comment critically on information concerning experimental procedures
j) comment on safety aspects of experiments based on supplied data or recall of the chemistry of the compounds listed in Units l and 2. Safety considerations should relate to specific experiments not be of a general nature
• it will be assumed that students wear eye protection during all practical work.

Here it is, positive rep would be very much appreciated.
I'll edit the document if I find any errors.
That's my C3B revision done.
(I would have included diagrams but the file size was too big)
Good luck everyone!
