Carbonic acid is heated
WebMar 29, 2024 · Carbonic acid attack occurs when carbon dioxide from the steam condenses with the condensate to form carbonic acid. The carbon dioxide originates from the thermal breakdown of the carbonate alkalinity naturally present in the makeup water. WebFeb 2, 2016 · Until now, little scientific attention has been lavished on the acid H 2 CO 3, commonly known as carbonic acid.Although known to form when carbon dioxide dissolves in water, carbonic acid reacts in a fraction of a second to form the more stable bicarbonate ion (HCO 3-), and therefore the concentration of the acid is so small under ambient …
