Complexometric titration- Used to determine hardness of water and concentration of metal ions. Water analysis- Measures calcium and magnesium in drinking or industrial water. Pharmaceutical and chemical labs- Used in quality control and metal ion analysis. Industrial testing- Applied in plating textile food and chemical industries.

The main purpose of 0.05 M EDTA volumetric solution is- to accurately measure and analyze metal ions in samples through titration and complex formation.

EDTA is a chelating agent that binds strongly with metal ions such as calcium magnesium zinc copper and iron. A 0.05 M EDTA solution is commonly prepared for analytical and titration work. It is usually colorless and water-based.
