Zeolite used to soften hardness of water is, hydrated
Options
(a) potassium aluminium borate
(b) sodium aluminium silicate
(c) zinc aluminium borate
(d) zinc aluminium silicate
Correct Answer:
sodium aluminium silicate
Explanation:
The process in which sodium aluminium silicate is used for the removal of temporary or permanent hardness of water is known as permutit process,whereby the Na⁺ ions of permutit (i.e., hydrated sodium aluminium silicate) are exchanged with Ca²⁺ and Mg²⁺ when hard water is passed through it. Na₂Al₂Si₂O₈.xH₂O + Ca²⁺/Mg²⁺ → CaAl₂Si₂O₈.xH₂O + 2Na⁺ or MgAl₂Si₂O₈.xH₂O.
