Which of the following statement is wrong regarding permanent hardness...
Permanent Hardness of Water

Definition: Permanent hardness of water is due to the presence of multivalent metallic ions such as calcium and magnesium in water which cannot be removed by boiling.

Factors Responsible for Permanent Hardness

The presence of sulfates, chlorides, and nitrates of calcium and magnesium is responsible for permanent hardness.

Methods of Removal

Permanent hardness of water can be removed by special methods of water softening such as:

1. Ion Exchange Method
2. Reverse Osmosis
3. Lime-Soda Process

Misconception Regarding Permanent Hardness

The statement "It is also called carbonate hardness" is wrong. Carbonate hardness is also known as temporary hardness which is due to the presence of bicarbonates of calcium and magnesium in water. Temporary hardness can be removed by boiling.

Conclusion

Permanent hardness is a type of water hardness that is different from temporary hardness in terms of its causes and methods of removal. It is important to understand the difference between the two types of hardness to choose the appropriate method of water softening.
