Deionization of impure water means:
- A- Boiling
- B- Filtration
- C- Exchange of protons and electrons.
The answer to this question is C. Exchange of protons and electrons.
Here's why:
- Boiling:
While boiling removes some impurities like microorganisms and bacteria through thermal death, it doesn't remove dissolved minerals and salts, which is the primary role of deionization.
- Filtration:
Filtration can remove larger particles and some contaminants but doesn't remove dissolved ions, which are targeted by deionization.
- Exchange of protons and electrons:
This accurately describes the process of deionization. Deionization systems use ion exchange resins to remove dissolved ions from water. These resins contain charged beads that attract and capture oppositely charged ions from the water, leaving it with low conductivity and minimal dissolved impurities.
Therefore, the exchange of protons and electrons is the most accurate definition of deionization in the context of impure water treatment.
