🧪 Normality Explained

N = Gram Equivalents / Volume (L)
N = Molarity × n-factor
  • n-factor for acids: number of H⁺ ions donated (HCl=1, H₂SO₄=2)
  • n-factor for bases: number of OH⁻ ions accepted (NaOH=1, Ca(OH)₂=2)

📖 Example

✅ H₂SO₄ Normality

0.1 M H₂SO₄ (n-factor = 2)

N = 0.1 × 2 = 0.2 N

❓ FAQ

What is normality?
Normality (N) is concentration in gram equivalents per liter. It accounts for the reactive capacity of each molecule. Normality = Molarity × n-factor.
When is normality used?
Normality is mainly used in titration (acid-base, redox) where equivalents are more relevant than moles. At equivalence point: N₁V₁ = N₂V₂.
