What is the rationale behind replacing undesirable ions using ion exchange in water treatment?

• A. To create a more acidic environment
• B. To enhance water's oxygen content
• C. To soften water for better health and usage
• D. To remove viruses from water

Answer: (C)

Replacing undesirable ions using ion exchange in water treatment primarily aims to soften water, which refers to the removal of hardness-causing minerals like calcium and magnesium ions. Hard water can cause scaling in pipes, reduce the efficiency of soap, and create undesirable deposits in plumbing fixtures and appliances. By exchanging these hardness-causing ions for sodium or potassium ions, water becomes softer and more user-friendly for washing, cooking, and drinking. This process is beneficial because softened water helps improve the effectiveness of detergents and soaps, leading to better cleaning results. Additionally, it minimizes the potential for plumbing issues caused by hard water deposits, ultimately prolonging the lifespan of water-using appliances and fixtures. This rationale highlights the significant health and operational benefits provided by softened water in everyday use.
