Permutit is hydrated Sodium Aluminium Orthosilicate having formula (Na2Al2Si2O8.xH2O). Permutit is a man-made zeolite.
Uses:
1. Softening of hard water.
2. As an adsorbent in separation method.
3. In Medicinal Chemistry.
Note:
It is used in the filtration of water, called permutit method. In this method, permutit is used to filter hard water by allowing the hard water to pass through it.
Preliminary observation is the record of the physical appearance of the supplied salt.
In preliminary observation, we note down State, Colour, Odour and Solubility.
State is either Crystalline or Amorphous.
The salt is called Crystalline, when it feels like sugar on rubbing on the palm of hand.
The salt is called Amorphous, when it feels like flour on rubbing on the palm of hand.
The colour of the salt is easily visible, so it will take least effort to find out.
Odour can be of various types –
If the salt smells like than of public toilet, it contains ammonium ion.
If the salt smells like rotten egg, it contains Sulphide ion.
If the salt smells like vinegar, it contains acetate ion.
Thanks for your time. 🙂

1. Group Theory and Chemistry by David M. Bishop
2. Chemical Application of Group Theory by F. Albert Cotton
3. Symmetry and Group Theory in Chemistry by Mark Ladd
4. Molecular Symmetry And Group Theory by Robert L. Carter
5. A Simple Approach To Group Theory in Chemistry by S Swarnalakshmi
6. Group Theory in Chemistry and Spectroscopy by B S Tsukerblat
7. Group Theory for Chemists by Keiran C. Molloy
8. Group Theory for Chemists by George Davidson
Do let us know if you have already read any of the mentioned book and also suggest any other group theory books that you have read in the comments.
