Soft water has a hardness of how many mg per liter or less?

• A. 30 mg
• B. 50 mg
• C. 80 mg
• D. 60 mg

Answer: (D)

Soft water is defined as water that contains a low concentration of dissolved minerals, particularly calcium and magnesium ions, which are responsible for water hardness. The classification of water hardness helps in understanding its characteristics and potential impact on water systems and usage. In the context of water quality standards, soft water typically has a hardness of 60 mg per liter or lower. This level of hardness indicates that the water contains minimal amounts of calcium and magnesium, making it less likely to cause scale buildup in plumbing and appliances. As a result, water with a hardness of 60 mg per liter or less is generally considered soft, providing benefits in terms of lower soap usage and cleaner rinsing for laundry and dishwashing. It's important for operators to recognize and manage the soft water classification effectively for treatment processes and customer satisfaction.
