What is the characteristic of "Soft water"?

a. Water that is not hard (does not contain salts that interfere with the formation of lather with soap)
b. Any celestial body orbiting around a planet or star
c. A cell that converts solar energy into electrical energy
d. The taste experience when salt is taken into the mouth

The correct answer is: a. Water that is not hard (does not contain salts that interfere with the formation of lather with soap)

Your choice is indeed correct. Soft water is characterized by its low mineral content, specifically, it has a minimal amount of calcium and magnesium salts. These minerals are typically responsible for causing water hardness. The significance of soft water lies in its ability to form lather easily with soap, making it more effective for cleaning purposes. Because it does not contain these ions, soft water can enhance the effectiveness of household cleaning products and reduce the scale buildup in plumbing systems and appliances. The other options describe entirely different concepts. The second choice refers to celestial bodies, which is unrelated to the properties of water. The third choice discusses a biological process involving cells converting solar energy into electrical energy, a concept related to photosynthesis and energy production but not water characteristics. The final option touches on taste perception associated with salt, which, while related to the sensory experience, does not pertain to the chemical properties of water.
