Options
- ATo neutralize the H⁺ ions released in the cation exchange process
- BTo increase water hardness
- CTo precipitate hardness ions
- DTo remove sodium ions
Correct answer
A. To neutralize the H⁺ ions released in the cation exchange process
Step-by-step solution
Hydroxide ions (OH–) in the anion exchange process neutralize the H⁺ ions released in the cation exchange process, maintaining the overall balance of ions in the water treatment process.
