Hard water contains calcium and magnesium ions, which react with the surfactant anion to give these metallic or lime soaps. [1] 2 C 17 H 35 COO − Na + + Ca 2+ → (C 17 H 35 COO) 2 Ca + 2 Na + In this reaction, the sodium cation in soap is replaced by calcium to form calcium stearate. Lime soaps build deposits on fibres, washing machines, and ...
In industrial scale water softening plants, the effluent flow from the re-generation process can precipitate scale that can interfere with sewage systems. [3] The slippery feeling associated with washing in soft water is caused by the weaker attraction of the soap to the water ions when the water has been stripped of its mineral content.
