What is the role of the cation exchange process in the water treatment method using resins?
Options
- ATo increase water hardness
- BTo remove all dissolved ions from the water
- CTo make the water acidic
- DTo exchange hardness ions for hydrogen ions
Correct answer
D. To exchange hardness ions for hydrogen ions
Step-by-step solution
The cation exchange process in the water treatment method using resins aims to exchange hardness ions (calcium and magnesium ions) for hydrogen ions (H⁺), resulting in the release of protons and making the water acidic.
