Tap water brings metal ions like calcium, magnesium, iron, or copper. These can cause precipitates (developer “scum”), catalyze oxidation, create stains, or reduce activity. Chelators bind these ions, keeping them harmless in solution. This improves reliability, especially with hard water, and prevents gritty deposits on film/paper or in tanks.

EDTA salts, hexametaphosphate, and citrates are typical.

In practice, they’re a “hidden stability upgrade” — you notice them most when they’re missing.
