Topics covered in Stoichiometry for JEE Advanced Chemistry.
Topics in Stoichiometry
Basic Concepts and Formulas
- Gram equivalent (Eq) = w/Ew, where w = weight and Ew = equivalent weight
- Milliequivalent (mEq) = w/Ew × 1000
- Equivalents = N × V(L) and mEq = N × V(mL)
n-Factors of Important Compounds
- KMnO₄: n=5 (acidic), n=1 (strongly basic), n=3 (neutral/mild basic)
- K₂Cr₂O₇: n=6 (always acts as oxidizing agent)
- H₂O₂: n=2 (both as oxidizing and reducing agent)
Disproportionation Reactions
- Single substance acts as both oxidizing and reducing agent
- Different n-factors for oxidation and reduction half-reactions
- Effective n-factor = (n₁ × n₂)/(n₁ + n₂) where n₁, n₂ are individual n-factors
Hydrogen Peroxide - Volume Strength
- Volume strength = Volume of O₂ produced at STP by 1mL H₂O₂
- 1N H₂O₂ = 5.6 volume = 1.7% = 17g/L
- Commercial H₂O₂: 3% = 10 volume, 30% = 100 volume
