(a) One burette of 50cm³ capacity
(b) One pipette either 20cm³ or 25cm³
All candidates at one center must use a pipette of the same volume. These should be clean and free from grease.
(c) The usual apparatus for titration.
(d) The usual apparatus for reagent 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) Barium chloride solution
(v) Acidified potassium dichromate solution
(vi) Aqueous ammonia
(vii) Lime water
(viii) Red and blue litmus papers
(ix) Dilute tetraoxosulphate (VI) acid.

(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/ diagnosed water
(m) Burning splint
(n) Watch glass
(o) Bunsen burner/ source heat
(p) Droppers
(q) Mathematical table/Calculator

(3) Each candidate should be supplied the following where n is the candidate’s serial number.
(a) 150cm³ of a solution HCL, in a corked flask or bottle labeled ‘An’. These should be all the same containing 9.0cm³ of concentrated HCL (about 36%) per dm³ of solution.

(b) 150cm³ of NaOH solution in a corked flask or bottle labeled ‘Bn’. These should all be the same containing 4.8g of NaOH per dm³ of solution.

(c) One spatulaful of a uniform mixture of CuSO4 and (NH4)2CO3 in a specimen bottle and corked immediately and labeled ‘Cn’. The components of the mixture should be in ratio 1:1 by mass.

(4) In all cases, more material may be issued if required.

(5) The actual concentration of ‘An’ and ‘Bn’ must be stated in the Supervisor Report Form. The candidate will assume that the concentrations are exactly as stated in the question paper.

(6) It should be noted that schools are not allowed to amend the information provided on the question paper or substitute any substance/solution for those specified in these instructions.



  1. The laboratory spaces should be serially numbered, and candidates should be assigned to them in the order of their index numbers.
  2. Every specimen given to a candidate should have the same number as his or her serial number.
  3. A candidate’s serial number should not be given to another candidate if he or she is absent.
  4. If the candidates are divided into multiple sets, the serial numbers should be carried over from set to set to ensure that no serial numbers are repeated.
  5. It should be ensured that candidates record their serial numbers as well as the index numbers at the start of the examination.

on the front pages of their answer books, as they will be marked according to their serial numbers.



  1. Separate Supervisor’s Report Forms are available. Each envelope of scripts must contain a completed Report Form.
  2. The titrations required of the candidates in Question 1 should be carried out by the chemistry teacher. The titration figures should be accurate to at least one decimal place and double-checked. Wide variations may occur if this is not done at the same time as the candidates’ own titrations, and the candidates may be unavoidably penalized.
  3. Any difficulties that a candidate has should be reported, especially if the Examiner would not be able to detect them from the scripts.



It’s critical to remind candidates that if chemicals aren’t handled properly, they can be dangerous. Read the following statements to the candidates before the practical examination begins.

“Even though the chemicals you’ll be working with have been carefully chosen, you’re being reminded that chemicals can be dangerous.” As a result, it’s critical that you handle them with care.
As soon as you notice anything unusual, bring it to the attention of your invigilator. If any chemical gets into your mouth, rinse it thoroughly with plenty of water. “As soon as you’ve finished handling the chemicals, wash your hands thoroughly.”

It is expected, however, that you will make the necessary arrangements to prevent any accidents from occurring.
