Soap is the sodium salt of a long chain fatty acid, Sodium salt stearic acis is soluble in water, whereas calcium and magnesium salts are insoluble, so when soap is added to soft water, it dissolves and forms lather readily. Temporary hardness in water can be easily removed by boiling. Permanent hardness can be removed by the addition of washing soda, Calgon process, ion exchange process. The degree of hardness of a sample of water containing 6 mg of magnesium sulphate (other salts are absent) per kilogram of water is
