Question

The most important salt that causes incrustation is: ________.
1. Calcium Carbonate
2. Sodium Chloride
3. Sodium Carbonate
4. Calcium Chloride

Answer 1

Correct Answer - Option 1 : Calcium Carbonate

Explanation:

Incrustation:

• The deposition of alkali salts on the inside wall of the tube well is known as incrustation.
• The most important salt causing incrustation is calcium carbonate.
• Sometimes the other salts such as calcium silicates & magnesium silicates may also lead to incrustation.
• The incrustation of the pipe reduces the diameter of the pipe hence reduces the discharge.

​

Corrosion:

If the water is highly acidic and it contains a lot of chlorides and sulphates then due to continuous action of such water the pipe may get corroded.
