The method that can be used to convert hard water to soft water is
Answer Details
Hard water contains high levels of dissolved minerals like calcium and magnesium, which can cause problems like soap scum, scale buildup, and decreased efficiency of water heaters and pipes. Soft water, on the other hand, contains very low levels of these minerals and is more desirable for household use. One effective method of converting hard water to soft water is the use of an ion-exchange resin. This resin contains sodium ions that can exchange with the calcium and magnesium ions in the water, effectively removing them and replacing them with sodium ions. This process is called ion exchange, and it can be done using a device called a water softener. Chlorination, passage over activated charcoal, and aeration are not effective methods of converting hard water to soft water.
