SPECIMENS PRACTICALS FOR CHEMISTRY
CHEMISTRY
PRACTICAL SPECIMEN:
1. Great care should be taken to ensure that
the information given in items 2 and
3belowdoes not reach the candidates either
directly or indirectly before the examination.
2. In addition to the fittings and reagents
normally contained in a chemistry laboratory,
the following apparatus and materials will be
required by each candidate.
a) One burette of 50cm³capacity.
b) One pipette, either 20cm³ or 25cm³.
All candidates at one center must use
pipettes of the same volume.
These should be clean and free from grease.
c) The usual apparatus for titration.
d) The usual apparatus and reagents for
qualitative work.
Including the following with all reagents
appropriately labelled.
i. Dilute sodium hydroxide solution.
ii. Dilute hydrochloric acid.
iii. Dilute trioxonitrate (v) acid
iv. Silver trioxonitrate (v) solution.
v. Barium chloride solution.
vi. Aqueous ammonia.
vii. Lime water.
viii. Red and blue litmus paper.
ix. Dilute tetraoxosulphate (VI) acid.
Content

e) Spatula
f) Filtration apparatus.
g) One beaker
h) One boiling tube
i) Four test tubes.
j) Starch solution as indicator.
k) Mathematical table/calculator
l) Wash bottle containing distilled/
deionized water.
3. Each candidate should be supplied
with the following Where n is the
candidate’s serial number.
(a) 150cm³ of sodium trioxosulphate (VI)
solution in a corked flask or bottle, Labelled
“An”.
These should all be the same containing 6.0g
of Na2S2O3 per dm³ of solution.
150cm³ of iodine in potassium iodide
solution in a corked flask or bottle labelled
“Bn”.
These should all be the same containing 2.5g
of I2 and 1.67g of KI per dm³ of solution.
One spatula full of a uniform mixture of
NaCl and CuCO3 in a specimen bottle
labelled “Cn”.
4. The components of the mixture
should be in the ratio 1:2 by mass
In all cases, more materials maybe issued if
required.
5. The actual concentrations of A and
B must be stated on the Supervisor’s
Report form.
The candidates will assume that the
concentrations are exactly as stated in the
question papers
