Question

In the Zeolite softening process, the Calcium and Magnesium present in water are precipitated as:

• A. Insoluble Sulfates
• B. Insoluble Zeolites
• C. Insoluble Chlorides
• D. Insoluble Carbonates

Answer 1

The correct option is B

Insoluble Zeolites

Explanation for the correct answer:-

Option (B):- Insoluble Zeolites

Zeolite softening:-

1. Zeolites are actually crystalline aluminosilicates , which are the porous solids.
2. A base exchanging method which is used for the treatment of hard water.
3. Zeolite softening is actually a process which is used for the removing of both the temporary as well as permanent hardness of the water
4. Zeolite softening is done by the precipitating of the Calcium and Magnesium that are present in water as insoluble zeolites.
5. In this process, there is an exchange of ${\mathrm{Ca}}^{2+}$ and ${\mathrm{Mg}}^{2+}$ions.

Therefore, the correct option is (B):- Insoluble Zeolites.
