How Water Hardness Affects Cleaning Action. Although soap is a good cleaning agent, its effectiveness is reduced when used in hard water. Hardness in water is caused by the presence of mineral salts like calcium (Ca) and magnesium (Mg) and occasionally iron (Fe) and manganese (Mn).

Cleaning Capacity of Soap with Hard and Soft Water (Theory ...

When soap is added to hard water, the Ca2+ and Mg2+ ions present in hard water react with soap. The sodium salts present in soaps are converted to their corresponding calcium and magnesium salts which are precipitated as scum. The insoluble scum sticks on the clothes and so the cleaning capacity of soap is reduced. The cleaning action of soap ...
