(1) Great care should be taken to ensure that the information given in items 2 and 3 below does 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 50.0 cm³ capacity;
(b) one pipette, either 20.0 cm³ or 25.0 cm³. (All candidates at one centre 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:
(3) Each candidate should be supplied with the following, where n is the candidate’s serial number.
(a) 150 cm³ of a solution of HCl, in a corked flask or bottle, labelled An’. These should all be the same containing 8.6 cm³ of concentrated HCI per dm³ of solution.
(b) 150 cm³ of NaHCO, solution in a corked flask or bottle labelled ’Bn’. These should all be the same containing 8.0 g of NaHCO3 per dm³ of solution.
(c) One spatulaful of 1:1 uniform mixture of copper (II) tetraoxosulphate (VI) and glucose in a specimen bottle labelled ’Cn’. This must be the same for all candidates
