According to the material, which general type is assigned to a titration described as Complexometric?

• A. Precipitation
• B. Complexometric
• C. Acid/Base
• D. Redox

Answer: (A)

In complexometric titration, metal ions are captured by a chelating agent to form a stable, soluble complex in solution. This binding, not proton transfer, electron transfer, or solid formation, defines the method. The titrant is typically a chelating agent like EDTA, and the endpoint is reached when all metal ions are tied up in complexes. That makes the general type Complexometric, because the core operation is complex formation with a ligand. Precipitation would involve forming an insoluble solid, which is not what happens in a complexometric titration.
