6.7.2. Neutralization

Try these first

1. 1.

   What is neutralization?

   Hint

   Think about the chemicals that balance acidity and alkalinity.

2. 2.

   Why is neutralization important in construction?

   Hint

   Consider the consequences of using untreated water.

3. 3.

   What is the purpose of neutralization in water used for construction?

   • To remove impurities
   • To balance pH levels
   • To increase temperature

   Hint

   Consider why pH levels are critical.

4. 4.

   True or False: Lime is used to neutralize alkaline water.

   • True
   • False

   Hint

   Think about whether lime is acidic or basic.

5. 5.

   You have a water sample with a pH of 4.5. How would you use lime to adjust this pH to within the acceptable range for construction? Outline your process.

   Hint

   Remember the relationship between lime quantity and pH adjustments.

6. 6.

   If a construction site tests its water and finds a pH of 11, what steps must be taken to ensure this water is neutralized? What reagent could be used?

   Hint

   Identify a suitable reagent that can address high pH levels.
