The usage of water in domestic and industrial applications require that it remain an effective solvent. When water is hard, it causes numerous problems. Soap, for instance, becomes ineffective in the presence of calcium and larger quantities are required to start its detergent action. Calcium ions present as Ca(HCO3)2 could also react to produce insoluble limestone, CaCO3. Precipitation of the latter is harmful to pipes because it can encrust the inner walls and eventually obstruct them. This can result in damaging both industrial machinery and home appliances like washing machines and dish washers.
