Which of the following describes water that has high mineral content, often leading to scaling?

Soft water
Hard water
Distilled water
Purified water

The correct answer is: Hard water

Hard water is characterized by a high concentration of dissolved minerals, particularly calcium and magnesium. When water with this composition is heated or evaporated, it leaves behind deposits of these minerals, which can cause scaling. Scaling can build up in pipes, fixtures, and appliances, leading to reduced efficiency and potential damage over time. In contrast, soft water contains fewer dissolved minerals, reducing the scaling tendency. Distilled water and purified water refer to forms of water that have been treated to remove impurities and minerals but do not specifically imply high or low mineral content. Therefore, the term that accurately describes water known for high mineral content and scaling is hard water.
