When a boiler water test indicates a pH value of 6, you should __________.

Question 1 of 27070

When a boiler water test indicates a pH value of 6, you should __________.

🔍 Key Concepts

• pH scale and what values mean for acidity vs. alkalinity in boiler water • Why boilers normally require slightly alkaline water to prevent corrosion and scale • Typical engineer’s response when pH is too low vs. when it is too high

💭 Think About

• On the pH scale, what does a value of 6 tell you about the water: acidic, neutral, or alkaline? • For boiler protection, do we normally want the water slightly acidic, neutral, or slightly alkaline? Why? • If the water is more acidic than desired, would you add a treatment that increases alkalinity, decreases alkalinity, or remove water by blowdown first?

✅ Before You Answer

• Confirm what pH 7 represents and how 6 compares to that • Recall which direction on the pH scale means more alkaline vs. more acidic • Think about which corrective action directly changes chemistry vs. which addresses contamination or excess solids (like blowdown or heater checks)

Question 1 of 27070

When a boiler water test indicates a pH value of 6, you should __________.

chemically treat to lower the pH to normal level

check the DC heater for possible malfunction

begin a continuous boiler blowdown

chemically treat to raise the pH to normal level
