Zeolite ia Sodium, Potassium salt of alumino silicate. The general formula of Zeolite is as
M x/n [(AlO2)x (SiO2)] · mH2O.
Where M= Na+, K+, NH4+, Li+, Ca+2, Mg+2
Examples: Na2[(AlO2)12 (SiO2)]·27H2O
Zeolite’s have truncated Octahedral structure.
Zeolite’s are molecular sieves (Chalni) , are used to removed hardness of water and sulphate unit from detergents.
H3BO3 is soluble in water and behaves as weak monobasic acid. It does not donate protons but rather it accepts OH- .Therefore it acts as a Lewis acid [B(OH)3] .It is not a proton donor because it accept lone pair or hydroxyl ion from water.

Why Boric acid become strong acid in the presence of cis 1,2-diol or 1,3-diol ?Boric acid exist as solid due to [ Boric [B(OH)3] ] hydrogen bonded together into two dimensional sheet.
When borax is strongly heated on loop of platinum wire, it loses water and form dehydrated disodium tetra borate which is swells into the white mass, which on further heating disodium tetra borate melts to form a transparent glassy solid called borax glass and borax bead.
When a solution of given salt is heated on bead , then volatile part of salt displaced by B2O3 and corresponding metaborates salt is formed which gives Characteristic colour on oxidizing and reducing flame and colour of the bead is noted in hot and cold for each type of flame. This is also called "BORAX BEAD TEST"

What is the molecular formula of Borax ?
What is the difference between the structure of AlCl3 and diborane?
They all act as bronsted base and accept proton from water like,
O−2+ H2O(l)→2OH−(aq)
2O2−+2H2O(l)→2OH−(aq)+H2O2(l)+O2(g)
We know that H+ accepters are base so alkali metal oxides(O-2), peroxides (O2-2) and superoxides (O-1/2) are abstract proton from water so they are Bronsted base.
