Question

what is softwater and hardwater write two methods for removal of hardness of water​

Answer 1

Answer:

Hard water is water that contains an appreciable quantity of dissolved minerals (like calcium and magnesium). Soft water is treated water in which the only ion is sodium. As rainwater falls, it is naturally soft. On the other hand, soft water tastes salty and is sometimes not suitable for drinking

Softening is the process of removing the dissolved calcium and magnesium salts that cause hardness in water. It is achieved either by adding chemicals that form insoluble precipitates or by ion exchange. Chemicals used for softening include calcium hydroxide (slaked lime) and sodium.
