Briefly explain about zeolites . |
|
Answer» Solution :Zeolites are alumino silicates having a three - dimensional cage like structure with a general formula `M_(x//n)^(n+) [ (AIO_(2))_(x) (SiO_(2))_(y) ] H_(2) O ` where M is a cation ion like `K^(+), Na^(+), Ca^(2+)`. These are obtained by replacing some of the silicon atoms by aluminium atoms. The aluminosilicate thus FORMED acquires negative charge and it is balanced by the cations like `Na^(+), K^(+) "or" Ca^(2+)` . Example : Feldspar - `KAISi_(3) O_(8)` and Zeolite - NAAI`(Si_(2) O_(6). H_(2)O)` |
