  • Month Administered: July 2026
  • Duration: 2 Hours 30 Minutes
  • Total Marks: 40 Marks
  • Number of Questions: 3 Questions (Questions 1 – 3)
  • Structure:
    • Question 1 (22 Marks): Quantitative analysis (Redox titration of ammonium iron(II) sulfate with KMnO4 and reaction kinetics of oxalic acid with KMnO4 at varying temperatures)
    • Question 2 (11 Marks): Qualitative inorganic analysis on salt mixture Solid P (dissolution, precipitation with NaOH, flame test, Ba(NO3)2 test, and KMnO4 redox reaction)
    • Question 3 (7 Marks): Qualitative organic analysis on Solid T (ignition/sootiness test, pH determination, NaHCO3 effervescence, and KMnO4 unsaturation test)

  It covers the following topics:

  • Quantitative redox titrations (standardization and stoichiometric mole ratio calculation between Fe2+ and acidified KMnO4)
  • Chemical kinetics and thermochemistry (measuring decolourisation times of oxalic acid and KMnO4 at varying temperatures and graphical plotting of 1/t against temperature)
  • Inorganic qualitative analysis (separation of residue and filtrate, metal cation confirmatory precipitation using NaOH and aqueous ammonia, flame test for sodium/calcium, sulfate/sulfite tests with Ba(NO3)2, and redox tests)
  • Organic qualitative analysis (flame combustion testing for aliphatic/aromatic nature, acidic functional group testing using sodium hydrogen carbonate, and saturation/unsaturation testing using acidified potassium manganate(VII))
