Field-by-Field Checklist

Part 1: Basic Chemistry

  • Atomic structure: electron configuration, ionization energy, electronegativity
  • Chemical bonds: ionic, covalent, metallic; intermolecular forces
  • Mole calculations: amount of substance, molarity, stoichiometry
  • Acids & bases: pH, neutralization titration, salt classification
  • Redox: oxidation numbers, batteries, electrolysis

Part 2: Theoretical Chemistry

  • Gas laws (PV=nRT), vapor pressure, phase diagrams
  • Thermochemistry (ΔH, Hess’s law)
  • Solution properties (boiling point elevation, freezing point depression, osmotic pressure)
  • Reaction rates & equilibrium (Kc, Le Chatelier’s principle)
  • Ionic equilibrium (Ka, Kw, buffers, Ksp)

Part 3: Inorganic Chemistry

  • Halogens (oxidizing power trend, HF anomaly)
  • Oxygen & sulfur (allotropes, Contact Process)
  • Nitrogen (Haber process, Ostwald process)
  • Alkali & alkaline earth metals (flame tests)
  • Transition metals (Fe²⁺/Fe³⁺, complex ions, systematic separation)

Part 4: Organic Chemistry

  • Structural formulas & isomers
  • Functional groups (-OH, -CHO, -COOH, -NH₂, etc.)
  • Oxidation stages (alcohol → aldehyde → carboxylic acid)
  • Aromatic reaction map (benzene → derivatives)
  • Structural determination methods

Part 5: Polymer Chemistry

  • Amino acids, proteins, carbohydrates, nucleic acids
  • Addition vs condensation polymerization

Comprehensive Exercise

Q1. Find the volume of 0.10 mol/L NaOH needed to neutralize 25.0 mL of 0.10 mol/L HCl, and name three concepts involved.

Solution

Volume:

caVa=cbVbc_a V_a = c_b V_b → 0.10×25.0=0.10×Vb0.10 \times 25.0 = 0.10 \times V_b → Vb=25.0 mLV_b = 25.0\,\mathrm{mL}

Three related concepts:

  1. Acid-base reaction (neutralization): H⁺ + OH⁻ → H₂O
  2. Amount of substance (mol): complete neutralization when acid mol = base mol
  3. Molarity: using c=n/Vc = n / V for the calculation

This shows how a single problem draws on knowledge from multiple areas.
