Sulfamic acid

Sulfamic acid (CAS No. 5329-14-6), with the molecular formula H3NO3S, is a white, crystalline, odorless solid. It is a strong inorganic acid that offers a unique combination of advantages: it is non-volatile, non-fuming, and relatively safe to handle compared to mineral acids like hydrochloric or sulfuric acid. It is highly soluble in water and effectively dissolves scale, rust, and hard water deposits without causing significant corrosion to most metals when used at appropriate concentrations and temperatures.
