Preparing for the WAEC Chemistry in general depends on how you performed on the practical. It’s usually difficult, especially when it comes to understanding and identifying the different specimens. I will provide you with WAEC chemistry specimens for 2025 below.

WAEC Chemistry Practical Specimen

WAEC Chemistry Practical Specimen for comes with guidelines, apparatus, materials, and labeled solutions for candidates. Make sure you follow the provided instructions and adhere to safety precautions during the examination.

Below are the Specimens

1. Guidelines and Precautions

• Great care should be taken to ensure that the information given in items 2 and 3 below does not reach the candidate either directly or indirectly before the examination.
• The examiner may assist candidates who are unable to proceed with an experiment after spending 15 minutes on it.
• Strict adherence to the regulations is required.

2. Apparatus and Materials

Candidates are required to have the following apparatus and materials:

• One burette of 50 cm3 capacity
• One pipette, either 20 cm3 or 25 cm3 (all candidates at one center must use pipettes of the same volume)
• The usual apparatus for titration
• Apparatus and reagents for qualitative work, including:
  • Dilute sodium hydroxide solution
  • Dilute hydrochloric acid
  • Dilute trioxonitrate (V) acid
  • Silver trioxonitrate (V) solution
  • Acidified potassium dichromate solution
  • Aqueous ammonia
  • Lime water
  • Red and blue litmus paper
  • Dilute tetraoxosulphate (VI) acid
  • Fehling’s solution A & B
• Spatula
• Filtration apparatus
• One beaker
• One boiling tube
• Four test tubes
• Methyl orange as an indicator
• Glass rod
• Wash bottle containing distilled/deionized water
• Burning splint
• Watch glass
• Bunsen burner/source of heat
• Droppers
• Mathematical table/calculator

3. Detailed Specimen Description

SPECIMEN (A): HYDROCHLORIC ACID SOLUTION (HCL)

• Each candidate will receive 150 cm3 of a solution of Hydrochloric Acid (HCl) labeled ‘An’ in a corked flask or bottle.
• All bottles labeled ‘An’ should contain the same solution with a concentration of 8.5 cm3 of concentrated HCl per dm3 of solution.
• Hydrochloric Acid is a strong acid commonly used in chemical laboratories for various experiments.

SPECIMEN (B): SODIUM CARBONATE DECAHYDRATE (NA2CO3·10H2O) SOLUTION

• Each candidate will receive 150 cm3 of a solution of Sodium Carbonate Decahydrate (Na2CO3·10H2O) labeled ‘Bn’ in a corked flask or bottle.
• 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 testing for the presence of carbonates.

SPECIMEN (C): GLUCOSE

• Each candidate will receive a spatulaful of glucose in a specimen bottle labeled ‘Cn’.
• All candidates should receive the same amount of glucose.
• Glucose is a simple sugar used in various experiments related to carbohydrates, such as testing for reducing sugars or conducting fermentation tests.

SPECIMEN (D): ZINC OXIDE (ZnO) POWDER

• The specimen labeled ‘Dn’ contains a spatulaful of zinc oxide powder.
• All candidates should receive the same amount of zinc oxide powder.
• Zinc oxide is a white, powdery compound commonly used in chemistry experiments and applications.

OTHER SPECIMENS

• WAEC Agricultural Science Practical Specimen
• WAEC Animal Husbandry Practical Specimen
• WAEC Fisheries Practical Specimen

Conclusion

Peparing for WAEC practicals is not an easy thing, I interviewed a group of student concerning their practical exam, about 80% of them were very nervous.

Only a few of them were confident of what they are going to do, so its always not easy but with dedication you can pass it with ease.
