Oxidation and Reduction — JAMB Chemistry Past Questions
Oxidation and Reduction is one topic inside the JAMB Chemistry syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Oxidation and Reduction questions with worked answers.
When JAMB examined Oxidation and Reduction
Oxidation and Reduction questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.
A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

Which of the following represents a redox reaction?
- A AgNO₃ + NaCl → AgCl + NaNO₃
- B H₂S + Pb(NO₃)₂ → PbS + 2HNO₃
- C CaCO₃ → CaO + CO₂
- D Zn + 2HCl → ZnCl₂ + H₂
Answer: D
Zn + HCl → ZnCl₂ + H₂ is redox.
In CH₃CH₂Cl + KCN → CH₃CH₂CN + KCl; cyanide is
- A Nucleophilic
- B Hydrophilic
- C Electrophilic
- D Hydrophobic
