1.	When Zeolite, which is hydrated sodium aluminium silicate is treated with hard water, the sodium ions are exchanged with which of the following ion(s) ?
Answer» `H^(+)` IONS `Mg^(2+)` ions `CA^(2+)` ions `SO_(4)^(2-)` ions Solution :Zeolite is USED to remove hardness of WATER. Zeolite is sodium aluminosilicate. It has a property to exchange `Ca^(2+)`and `Mg_(2+)`. ions from hard water by `Na^(+)`ION of zeolite.
