1.	Assertion : Zeolites are the three-dimensional network silicates. Reason : Negative charge on zeolite structure is neutralised by positively charged AI^(3+) ions.
Answer» SOLUTION :ZEOLITES are the three-dimensional aluminosilicates in which few Si atoms are replaced by AI atoms. The Acquired NEGATIVE charge on zeolite structure is balanced by cations such as `NA^(+), K^(+)` or `CA^(2+)`, etc.
