WebThe first chemical treatment for softening hard water — lime softening — was invented by the chemist Thomas Clark (like Gibb, also a Scott) in the 1830s. The process consists of adding a solution of calcium hydroxide (lime water). This process precipitates any calcium bicarbonate present in the water, along with the added calcium and some ...

Solved hard water is passed through an ion-exchange material
WebJan 10, 2012 · Ion exchange is commonly used to soften water. During ion exchange, hard water is passed through a cylinder filled with resin beads that have been saturated with sodium. When this happens, the hardness ions are attracted to the resin and the sodium ions are released. WebHard water contains C a and M g salt so when it is passed through negative ion exchange resin, it capture cations from water and make it free from C a + 2.
