School Instructions
- Preserve confidentiality: Prevent any direct or indirect communication of the provided information to candidates before the exam.
- Required materials: Candidates must have standard chemistry lab equipment, a 50cm³ burette, a 20cm³ or 25cm³ pipette (uniform for all candidates in a center), filtration apparatus, and reagents for qualitative work.
- Additional Apparatus Candidate supplies: Each candidate receives a corked flask labeled ‘An’ with 150 cm³ of tetraoxosulphate (VI) solution and another labeled ‘Bn’ with 150 cm³ of Na2C03 solution.
The Teachers Report
The Teacher’s report must specify the concentrations of solutions A and B, with candidates using the concentrations provided in the question paper.

No substitutions: Candidates are not allowed to substitute any substance or solution mentioned in the instructions.
Arrangement of candidates: Assign serial numbers to candidates in the laboratory in sequential order based on the examination number.
Specimen numbering: Ensure each candidate’s specimen numbers continue without repetition throughout the sets.
Division into sets: If candidates are in sets, maintain a continuous serial number to avoid repetition.
Record information: Candidates must note their serial numbers and registration numbers on the front page of their answer booklets at the start of the examination. Enclose a completed Teacher’s Report form with each script envelope.
Titration requirements
- (a)One burette (50cm³)
- (b) One Pipette (20cm³ or 25cm³)
- However, all candidates in a centre must use pipettes of the same volume
- (c) The usual apparatus for filtration
- (d) The usual apparatus and reagent for qualitative work including:
- (i) Dilute sodium hydroxide solution
- (ii) Dilute ammonia solution
- (ii) Dilute hydrochloric acid
- (iv) Barium Chloride solution
- (v) Distilled water
- (vi) Red and blue litmus paper
- (vi) Phenolphthalein
- (vii) Methyl orange
- (ix) One boiling tube
- (x) Five test tubes
- (xi) Source of heat
- (xi) Wash bottle containing distilled water
- (xii) Filtration apparatus
- 3. Each candidate should be supplied with the following:
- where ‘n’ is the candidate’s serial number
- (a) 150 cm³ of tetraoxosulphate (VI) solution in a corked flask or bottle labelled ‘An. These should all be the same containing 2.20cm³ of
- concentrated tetraoxosulphate (Vi) acid per dm³ of solution.
- (b) 150 cm3 of Na2C03 in a corked flask or bottle labelled ‘Bn’. These should all be the same containing 3.6 g of sodium trioxocarbonate (IV)
- pellet per dm3 of solution.
- (c) One spatula of Na2C03 in a corked
- specimen bottle labelled ‘Cn’. Note ‘n’ is the candidate’s serial number.
- In all cases, more materials may be given if required
Conduct the required titration for question one, recording titre values with at least one decimal place on the Teacher Report Form, verifying them before documentation.
Report difficulties: Report any challenges faced by candidates, especially those not evident in the scripts.
- Include a completed Teacher’s Report form in each script envelope; this form is provided separately.
- Perform the required titration for question one, recording titre values with at least one decimal place in the designated spaces on the Teacher Report Form. Ensure the values are verified before recording.
- Report any difficulties experienced by candidates, particularly those not apparent from the scripts.
Prepare thoroughly for chemistry practical exams by mastering the concepts, theories, and formulas relevant to each experiment. Familiarize yourself with the aim of each experiment to enhance your recall of the procedures during the examination.
Conclusion
NECO has released the official Chemistry Specimen for the 2024 examination. Acknowledging the crucial role of practicals in exam success, we provide comprehensive materials for the Chemistry practical examination, including the identification of Specimens ABC and D.
The National Examinations Council, a prominent examination body in Nigeria, conducts the Senior Secondary Certificate Examination and the General Certificate in Education in June/July and December/January sessions.
Chemistry Lab Report
A lab report is a detailed document that outlines the procedures, methods, results, and conclusions of a scientific experiment or investigation conducted in a laboratory setting.
Lab reports are commonly used in academic and professional settings to communicate the findings of experiments and research. In the context of a chemistry lab report, the document typically follows a structured format.
