In water treatment, chelation is applied primarily to prevent which condition?

Explanation:
Chelation in water treatment works by binding metal ions such as calcium and magnesium, keeping them dissolved rather than letting them form solids. When hardness minerals precipitate, they create scale on pipes, heat exchangers, and equipment, which can reduce efficiency and cause blockages. Chelating agents form stable complexes with these ions, preventing this deposition and protecting the system. While chelation can also influence the appearance of iron-related color by keeping iron in solution, the primary effect tied to the given scenario is preventing scale formation.
