Hard Water - Chemistry LibreTexts
Aug 18, 2020· Temporary Hard Water Temporary hard water is hard water that consists primarily of calcium (Ca 2 +) and bicarbonate (HCO 3-) ionsHeating causes the bicarbonate ion in temporary hard water to decompose into carbonate ion (CO 3 2-), carbon dioxide (CO 2), and water (H 2 O) The resultant carbonate ion (CO 3 2-) can then react with other ions in the solution to form insoluble ,...
