Complexometric titration- Used to determine concentration of metal ions. Water hardness testing- Measures calcium and magnesium levels in water. Pharmaceutical analysis- Used in quality control and assay procedures. Industrial and chemical analysis- Applied in electroplating textile and food industries for metal analysis.

The main purpose of 0.1 M EDTA volumetric solution is- to accurately detect measure and quantify metal ions in laboratory and industrial samples through titration.

EDTA is a strong chelating (metal-binding) agent. It forms stable complexes with metal ions like calcium magnesium iron copper and zinc. A 0.1 M solution is commonly used in laboratories for quantitative chemical analysis.
