Topic 3.1B: Laboratory chemistry

return to unit 3

Summary of content

Students will be expected to:

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. recognize 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 distilling 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
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.
