It is of utmost importance to ensure that the information contained in items 2 and 3 below does not reach the candidate either directly or indirectly before the examination.

In addition to the standard fittings and reagents typically found in a chemistry laboratory, each candidate will require the following apparatus and materials:

1. One burette with a capacity of 50 cm3.
2. One pipette, either 20 cm3 or 25 cm3. (All candidates at a single center must use pipettes of the same volume, and these should be clean and free from any grease).
3. The usual apparatus for titration.
4. The usual apparatus and reagents for qualitative work, including the following with all reagents appropriately labeled: (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.
5. Spatula.
6. Filtration apparatus.
7. One beaker.
8. One boiling tube.
9. Four test tubes.
10. Methyl orange as an indicator.
11. Glass rod.
12. Wash bottle containing distilled/deionized water.
13. Burning splint.
14. Watch glass.
15. Bunsen burner/source of heat.
16. Droppers.
17. Mathematical table/calculator.

Additionally, each candidate should be provided with the following items, where 'n' represents the candidate's serial number:

1. 150 cm3 of a solution of HCl in a corked flask or bottle labeled 'An.' All bottles labeled 'An' should contain the same solution, with a concentration of 8.5 cm3 of concentrated HCl per dm3 of solution. This solution is a strong acid commonly used in chemical laboratories for various experiments, including titration and acid-base reactions.

2. 150 cm3 of Na2CO3·10H2O in a corked flask or bottle labeled 'Bn.' All bottles labeled 'Bn' should contain identical solutions with a concentration of 5.0 grams of the hydrated salt per dm3 of solution. Sodium Carbonate Decahydrate is a white crystalline compound used in chemical experiments, particularly in titrations and carbonate testing.

3. A spatulaful of glucose in a specimen bottle labeled 'Cn.' All candidates should receive the same amount of glucose. Glucose is a simple sugar and is essential as an energy source for living organisms. It may be used in various experiments related to carbohydrates during the practical examination.

4. A spatulaful of zinc oxide powder in a specimen bottle labeled 'Dn.' All candidates should receive the same amount of zinc oxide powder. Zinc oxide is a white, powdery compound commonly used in chemistry experiments, particularly in reactions involving metal oxides or in the preparation of other compounds. Safety precautions should be followed when handling this substance in the laboratory.
