Explanation:
Water is classified as either soft or hard:
Soft water contains relatively few minerals and lathers easily.
Hard water is rich in minerals such as calcium and magnesium, which is the cause of “scale” in kettles.
Water hardness is usually expressed as the number of parts per million (ppm) of calcium carbonate present in the water
