Question

When zeolite, which is hydrated sodium aluminum silicate is treated with hard water, the sodium ions are exchanged with

Answer 1

Sodium zeolite removes Ca2+ and Mg2+ ions from hard water. Na2Z + M2+ → MZ + 2Na+ (M = Ca, Mg) where, Z = Al2Si2O8H2O

Answer 2

When zeolite, which is hydrated sodium aluminium silicate, is treated with hard water, the sodium ions are exchanged with

Mg2+ions’

Ca2+ ions

Sodium zeolite removes Ca2+ and Mg2+ ions from hard water. Na2Z + M2+ → MZ + 2Na+ (M = Ca, Mg) where, Z = Al2Si2O8H2O
