Used as a cleaning agent in industrial and household applications, particularly for removing mineral deposits, rust, and scale from metal and ceramic surfaces. Effective in boiler and heat exchanger cleaning due to its ability to dissolve iron oxides and other inorganic residues. Also serves as a corrosion inhibitor when added to water treatment systems, helping protect metal components in cooling circuits. Employed in the formulation of herbicides and other agrochemicals, where it enhances the stability and solubility of active ingredients. Its buffering properties make it useful in pH control during various chemical processes.
