Fundamentals of Volumetric Analysis
Volumetric analysis (titrimetry) me known concentration ke solution (titrant) ko unknown solution (analyte) ke saath tab tak milate hain jab tak reaction poora na ho jaye.
- Standard solution: jis ki exact concentration pata ho
- Primary standard: bahut pure, stable, non-hygroscopic substance, jaise oxalic acid, sodium carbonate
- End point: jahan indicator ka rang badalta hai
- Equivalence point: jahan reactants chemically barabar ho jate hain
- Molarity, Normality aur Molality concentration ke units hain
Acid-Base Titration
Isme acid aur base ka neutralization hota hai. Indicator ka selection titration ke type par depend karta hai.
| Titration | Suitable indicator |
|---|---|
| Strong acid vs strong base | Phenolphthalein ya methyl orange |
| Weak acid vs strong base | Phenolphthalein |
| Strong acid vs weak base | Methyl orange ya methyl red |
Non-Aqueous Titration
Jo weak acids aur bases paani me sahi se titrate nahi hote, unke liye non-aqueous solvents use hote hain. Weak bases ke liye glacial acetic acid me perchloric acid titrant hota hai aur indicator crystal violet hota hai. Isse amines aur alkaloid salts ka assay hota hai.
Precipitation Titration (Argentometry)
Isme silver nitrate se halide ions ko precipitate kiya jata hai. Teen main methods hain:
- Mohr method: potassium chromate indicator, neutral ya halka alkaline medium
- Volhard method: back titration, ferric alum indicator, acidic medium
- Fajans method: adsorption indicator jaise fluorescein
Complexometric Titration
Isme metal ions ke saath EDTA complex banata hai. Yeh calcium, magnesium aur zinc jaise metals ke assay me use hota hai. Common indicator Eriochrome Black T hai, aur medium pH 10 ke aas-paas ammonia buffer se banaya jata hai.
Redox Titration
Isme oxidation aur reduction saath hote hain.
- Permanganometry: KMnO4 self indicator hai (halka pink rang end point par)
- Iodimetry: iodine direct titrant ki tarah
- Iodometry: liberated iodine ko sodium thiosulphate se titrate karte hain, indicator starch

FAQs – Volumetric Analysis
Primary standard kya hota hai?
Primary standard bahut pure, stable aur non-hygroscopic substance hota hai jisse standard solution banate hain, jaise oxalic acid.
Complexometric titration me kaunsa indicator use hota hai?
Eriochrome Black T, pH 10 ke aas-paas ammonia buffer ke saath.
KMnO4 ko self indicator kyun kehte hain?
Kyunki end point par uska halka pink rang khud dikhne lagta hai, alag indicator ki zaroorat nahi padti.
