Verified answer
Ca2+ + Na4P6O182- ? 2Na+ + CaNa2 P6O182- From hard water Anion of calgon Goes into solution This results in the removal of calcium and magnesium ions from hard water in the form of a complex with Calgon. The water is softened and sodium ions are released into water.
Hope it helps.
Answer:
Adding Calgon to rough water results in sodium ions being separated from Calgon's anion by hard water calcium and magnesium ions. The effect is the extraction from hard water, in the form of a Calgon complex, of calcium and magnesium ions. It softens the water and releases sodium ions.
