(a) one burette of 50 cm³ capacity:
(b) one pipette.eiter 20 cm³ or 25 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:

(i) dilute sodium hydroxide solution;
(ii) dilute hydrochloric acid;
(iii) dilute trioxonitrate(V)acid:
(iv) silver trioxonitrate (V) solution;
(v) acidified potassium dichromate solution;
(vi) aqueous ammonia;
(vii) lime water;
(viii) red and blue litmus paper;
(ix) dilute tetraoxosulphate (VI) acid;
(x) fehlings solution A& B.

(e) spatula;
(f) filtration apparatus;
(g) one beaker
(h) one boiling tube;
(i) four test tubes;
(j) methyl orange as indicator;
(k) glass rod;
(l) wash bottle containing distilled/deionized water;
(m) burning splint:
(n) watch glass;
(o) Bunsen burner/source of heat:
(p) droppers;
(q) mathematical table/calculator.

3. Each candidate should be supplied with the following, where ‘n’ is the candidate’s serial number.

(a) 150 cm³ of a solution of HCI in a corked flask or bottle labelled ‘An’. These should all be the same contining 8.5 cm³ of concentrated HCI per dm³ of solution.

(b) 150 cm3 of Na2CO3.10 H,O in a corked flask or boutle labelled ‘Bn’, These should all be the same containing 5.0g of the hydrated salt per dm³ of solution.

(e) One spatulaful of glucose in a specimen bottle labelled ‘Cn’.This must be the same for all candidates.

(d) One spatulaful of zinc oxide powder in a specimen bottle labelled ‘Dn’. This must be the same for all candidates.

4. In all cases,more materials may be 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 paper.

7. The laboratory places should be numbered serially and the candidates should be allotted these places strictly in the order of their index numbers.

The number of every specimen supplied to each candidate should be the same as his or her serial number.

8. If a candidate is absent, his or her serial number should not be allotted to another candidate.

9. If the candidates are divided into a number of sets, the serial numbers should be continued through the sets, so that no serial number is repeated.
