Vedclass · Answer

(C) Hydrated sodium aluminium silicate $(Na_2 Al_2 Si_2 O_8 \cdot x H_2 O)$ is known as permutit or zeolite.During the water softening process,the $Na^+$ ions in the permutit are replaced by $Ca^{2+}$ or $Mg^{2+}$ ions present in the hard water.When all the $Na^+$ ions are replaced by $Ca^{2+}$ or $Mg^{2+}$ ions,the permutit is said to be exhausted.Therefore,exhausted permutit is $Ca Al_2 Si_2 O_8 \cdot x H_2 O$ (or the corresponding magnesium salt).
