About Eduqas A Level Chemistry PI2.2 Chemistry of the d-block Transition Metals
This topic covers transition metal chemistry. Expect colour and ligand questions.
What you need to know
- Definition Transition elements form at least one ion with a partially filled d sub-shell.
- Complex ions Ligands form dative bonds; octahedral and tetrahedral shapes.
- Colour d-orbital splitting; light absorbed promotes electrons and the complementary colour is seen.
- Catalysis Variable oxidation states make transition metals good catalysts.
Common mistakes in PI2.2 Chemistry of the d-block Transition Metals
- Including zinc as a transition element.
- Saying colour is due to light emitted.
- Mixing up ligand exchange colours.
Try three PI2.2 Chemistry of the d-block Transition Metals exam-style questions
1. Explain why Cu²⁺ complexes are coloured. (2 marks)
Show the mark scheme answer
Ligands split d orbitals (1); electrons absorb certain frequencies of visible light, and the rest is transmitted (1).
2. State the colour of [Cu(H₂O)₆]²⁺. (1 mark)
Show the mark scheme answer
Blue.
3. Explain why transition metals are good catalysts. (1 mark)
Show the mark scheme answer
They have variable oxidation states so can gain and lose electrons easily.
