📖 Theory & Concepts ▼
Primary Standard: A substance of known high purity used to prepare solutions of exact concentration.
Oxalic Acid: H₂C₂O₄·2H₂O, Mol. Wt. = 126 g/mol, Eq. Wt. = 63 g/eq
Na₂CO₃: Mol. Wt. = 106 g/mol, Eq. Wt. = 53 g/eq
Normality = (Weight × 1000) / (Eq.Wt. × Volume in mL)
Key: For 0.1N in 250mL → Oxalic acid: 1.575g, Na₂CO₃: 1.325g
