Q. Which of the following statements are correct about zeolite?
$1.$ Zeolites are aluminosilicates having three dimensional network
$2.$ Shape selectivity of zeolites depends upon porous structures of the catalyst
$3.$ Zeolites are synthetic microporous aluminosilicates which do not exist naturally
$4.$ Zeolites are open structures of silica in which trivalent aluminium substitute by a fraction of silicon atoms

Solution:

Zeolites are naturally occurring or synthetic microporous aluminosilicates which are used to remove permanent hardness from hard water. Shape selectivity of zeolites depends upon porous structures of the catalyst.
