Which of the following describes a characteristic of soft water?

• A. High pH levels
• B. Low mineral content
• C. High levels of calcium and magnesium
• D. Increased clarity and absorption

Answer: (B)

Soft water is characterized by low mineral content, particularly with respect to calcium and magnesium ions, which are typically responsible for water hardness. When water is referred to as "soft," it indicates that it has been treated or filtered to remove these minerals, resulting in a smoother taste and less scaling in plumbing systems and appliances. Soft water can occur naturally in areas where the geology does not contain limestone or other minerals that contribute to hardness, but it can also be produced through ion exchange processes or water softening systems. In contrast, high pH levels, high levels of calcium and magnesium, and increased clarity or absorption do not align with the definition of soft water. High pH levels tend to indicate more alkalinity and might be found in hard water conditions. Elevated calcium and magnesium levels are the defining aspects of hard water, making it more difficult for soap to lather and often leading to the buildup of scale in pipes and appliances. Increased clarity and absorption may be desirable characteristics in certain contexts, but they do not specifically describe the mineral content and overall hardness that define soft water.
