When zeolite (Hydrated sodium aluminium silicate) is treated with hard water the sodium ions are exchanged with.

A

OH−OH^{-} ions

B

SO42−SO_{4}^{2 -} ions

C

Ca2+Ca^{2 +} ions

D

H+H^{+} ions

Answer

Ca2+Ca^{2 +} ions

Explanation

Solution

Na2Al2Si2O8Zeolite.xH2O+Ca+2→\underset{\text{Zeolite}}{Na_{2}Al_{2}Si_{2}O_{8}}.xH_{2}O + Ca^{+ 2} \rightarrow

CaAl2Si2O8.xH2O+2Na+CaAl_{2}Si_{2}O_{8}.xH_{2}O + 2Na^{+}
