What do we call water having a low concentration of calcium and magnesium?

• A. Hard water
• B. Mineral water
• C. Soft water
• D. Brackish water

Answer: (C)

Water that has a low concentration of calcium and magnesium is referred to as soft water. This type of water is characterized by its ability to easily lather with soap and does not leave scale deposits on fixtures and appliances. It is often desirable for household uses, such as washing and bathing, because it can enhance the effectiveness of soaps and detergents. Soft water can occur naturally in areas where the geology does not contain the minerals that contribute to hardness, or it can be produced through water treatment processes such as ion exchange, where hardness ions are replaced with sodium or potassium ions. Understanding the distinctions between soft water and other types of water is important for water quality management and service provision in the field of water treatment. Soft water is particularly beneficial for reducing the buildup of deposits in plumbing systems and improving the longevity of water-using appliances.
