Limescale is a hard, chalky deposit, consisting mainly of calcium carbonate (CaCO 3). It often builds up inside kettles, boilers, and pipework, especially that for hot water. It is also often found as a similar deposit on the inner surfaces of old pipes and other surfaces where hard water has flowed.
A bathtub faucet with built-up calcification from hard water in Southern Arizona. Hard water is water that has a high mineral content (in contrast with "soft water").

Hard water refers to water that contains a high amount of minerals. Water picks up impurities very easily as it moves through the rock and soil. Calcium and magnesium are the main culprits when it ...
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 ...
Drinking water from nearly half of U.S. faucets likely contains “forever chemicals” that may cause cancer and other health problems, according to a government study released Wednesday. The ...
