Question

zeolite chemical formula.​

Answer 1

$\textsf{\underline{\Large{p-Block Elements}}}$

$\textsf{\underline{\Large{ZEOLITES}}}$ :

$\textsf{\underline{\large{General Chemical Formula of Zeolites}}}$ :

$\boxed{\mathsf{M_{\tiny{\dfrac{x} {n}}}\:[\:AlO_2\:]_x\:[\:SiO_2\:]\:.\:mH_{2}O}}$

Zeolites are "aluminosilicate" obtained when " Al " - atoms replace few " Si" - atoms in 3 - D network of $\mathsf{SiO_2}$.

$\textsf{\underline{Example}}$ : Feldspar $\mathsf{(\:KAlSi_3O_8\:)}$ & zeolites $\mathsf{(\:NaAlSi_2O_6.H_{2}O\:)}$.

$\textsf{\underline{\large{Applications of Zeolite}}}$ :

1 ). As a catalyst in petrochemical industries for cracking of hydrocarbons.

2 ). ZSM - 5 [ a type of Zeolite, ZSM = Zeolite Sieve Membrane { Numeral 5 indicates the size of pores} ] used to convert alcohols directly into gasoline ( petrol ).

3 ). Hydrated zeolites are used as "ion exchangers" in softening of ' hard water'.

Answer 2

What is Zeolites?

A shape-selective catalyst having Honeycomb structure which permit only selective molecules.

Formula: Mx/n [(AlO₂)x (SiO₂)y].zH₂O

Application of Zeolites:

1. Acts as water softener & selective absorbents.
2. Used as "ions-exchanger" in softening of hard water.
3. For cracking of Hydrocarbons & Isomerization.
