According to the material, Acid/Base titration corresponds to which general type of titration?

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

Answer: (C)

Titration types are categorized by the chemical reaction that drives the change at the endpoint. An acid/base titration relies on acid–base neutralization, where an acid donates protons and a base accepts them, producing water and a noticeable change in pH as you approach the equivalence point. This is detected with an acid/base indicator or a pH meter. It’s distinct from precipitation titration (which depends on forming a sparing insoluble solid), redox titration (which hinges on electron transfer), or complexometric titration (which tracks the formation of a metal–ligand complex, often with EDTA). So the general type for an acid/base titration is, itself, an acid/base titration, not complexometric.
