Q

A common gas dissolved in water contributing to the greatest amount of corrosion in a condensate system is __________.

🔍 Key Concepts

• Dissolved gases and corrosion in condensate and boiler systems • How acids form from gases when they dissolve in water and lower pH • Difference between inert gases and reactive gases in causing corrosion

💭 Think About

• Which of these gases, when dissolved in water, is most likely to form an acidic solution that attacks metal surfaces in a condensate system? • Which gases listed are mostly inert (do not easily react) and therefore are less likely to directly cause corrosion? • Think about boiler water treatment: which gas do engineers work hard to remove or neutralize because of the carbonic acid it can create?

✅ Before You Answer

• Identify which gas can form carbonic acid when dissolved in water • Eliminate gases that are largely inert in water and do not significantly change pH • Recall which gas is specifically targeted in condensate and feedwater chemistry discussions for causing grooving and pitting in lines
