Manufacturing Quality Control of Potassium tartrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Potassium Tartrate Content) | Acid-Base Titration | Neutralization of tartrate anion with standardized NaOH after acid hydrolysis and back-titration. |
| Loss on Drying | Gravimetric Method (Thermogravimetry) | Mass loss measured after drying at 105 C for 2 h under controlled humidity conditions. |
| pH of Aqueous Solution | pH Potentiometry | Measurement of hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Chloride Impurity | Argentometric Titration (Mohr Method) | Titration with standard AgNO3 solution using K2CrO4 as indicator to form red Ag2CrO4 endpoint. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitation of sulfate as BaSO4 followed by ignition and weighing of the dried precipitate. |
| Heavy Metals (as Pb) | Colorimetric Limit Test (Thiourea Method) | Reaction with thiourea in acidic medium to form colored complex; compared visually against lead standard. |
| Iron Impurity | UV-Vis Spectrophotometry | Formation of orange-red Fe-1,10-phenanthroline complex measured at ~510 nm. |
| Arsenic Impurity | Gutzeit Limit Test | Generation of arsine gas from sample under acidic conditions, reacted with mercuric bromide paper to yield yellow stain. |
| Residue on Ignition | Gravimetric Method | Weight of non-volatile residue remaining after incineration at 600 C in a platinum crucible. |
| Water Content (Karl Fischer) | Coulometric Karl Fischer Titration | Electrochemical generation of iodine to react stoichiometrically with water; quantified via charge measurement. |
