Why is the pH of the medium important in edta titration?

The pH of the medium is important in EDTA titration because the formation of the metal-EDTA complex depends on the pH. At certain pH levels, the metal-EDTA complex formation is optimized, leading to accurate results. Deviations from the optimal pH can affect the stability of the complex and lead to incorrect titration results.
