Calgon process
Calgon is a trade name of a complex salt, sodium hexametaphosphate
(NaPO3)6. It is used for softening hard water. Calgon ionizes to give a complex anion:
The addition of Calgon to hard water causes the calcium and magnesium ions of hard water to displace sodium ions from the anion of Calgon.
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.

All the best.

Dear Student,
Please find below the solution to your problem.
Calgon is a trade name of a complex salt, sodium hexametaphosphate(NaPO3)6.
It is used for softening hard water.
Calgon ionizes to give a complex anion:
[ionization of calgon]
The addition of Calgon to hard water causes the calcium and magnesium ions of hard water to displace sodium ions from the anion of Calgon.
[addition of Calgon to hard water]
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.
Thanks and Regards
