As per your syllabus, the reaction Cl₂(g) + 2 KI(aq) → 2 KCl(aq) + I₂(s) is an example of which kind?
- Disproportionation
- Decomposition
- Combination
- Halogen displacement
Show answer and solution
Correct answer: D. Halogen displacement
Your syllabus: stronger oxidiser Cl₂ displaces I⁻ from KI.
Basis of 'Layer Test' for halide identification.
As per your syllabus, the balanced reaction of MnO₄⁻ with Br⁻ in BASIC medium gives MnO₂ and which Br species?
- BrO₃⁻
- BrO⁻
- Br⁻
- Br₂
Show answer and solution
Correct answer: A. BrO₃⁻
syllabus Problem 7.9: 2 MnO₄⁻ + Br⁻ + H₂O → 2 MnO₂ + BrO₃⁻ + 2 OH⁻. Mn 7→4, Br −1→+5.
