Explain permutit process ion exchange process ?

Ions get exchanged. The calcium and magnesium get trapped in zeolite and sodium ion passes from the zeolite to water thus, hard water becomes soft as the calcium and magnesium ion removes from water and sodium permutit converts into calcium and magnesium permutit.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
