1.	Write any 1 disadvantages of hardness of water
Answer» (i) Washing: Hard water, when used for washing purposes, does not LATHER freely with soap. On the other hand, it produces sticky PRECIPITATES of calcium and MAGNESIUM SOAPS. The formation of such insoluble, sticky precipitated continues, TILL all calcium and magnesium salts present in water are precipitated. After that, the soap (e.g., sodium stearate) gives lather with water.
