Ions which are typically exchanged in a water softening system should be recognized along with a conclusion about the relative numbers of various ions involved given that the ion exchanger cannot build up a large positive charge. Concept introduction: Water softening means removal of calcium, magnesium ions salts from hard water. Because of these two ions, basicity will increase in the water. Hard water cannot be used for drinking, because it could form precipitates in our body. Drinking hard water is a waving hand for very dangerous diseases. So, we have to remove these ion containing salts. Water hardening can be divided into two; permanent hardening and temporary hardening. We can use many methods to remove this ion salts. One of the removing processes is using a resin. This is a healthy method.
