This Department saw its inception in 1949 in the old premises. Prof. G.S.Kotwani. a renowned author of Chemistry text books, was the first head. TheDepartment participates in inter-disciplinary teaching e.g. the History syllabus at theTYBA level has a chapter dealing with Chemistry of Preservation. The Department helps inteaching this topic. The Commerce syllabus at the SYBCom level includes a chapter dealingwith the environment which also involves some chemistry which the department helps inteaching.
The Department undertakes excursions and visits to industrial units togive the students a hands-on practical view of the theories learnt in class. Besides this,the department regularly sends its students to participate in various inter-collegiateQuiz competitions on Chemistry.
The Chemical Society has an excellent library whichincludes several rare collections of books on diverse subjects related to Chemistry togive the students a distinctive edge in their preparations and future careers.
At the Sixth International Symposium on Advances inElectrochemical Science and Technology from the 26th - 28th Nov. 1998 at Chennai,India, organised by the Society for Advancement of Electrochemical Science andTechnology, Karaikudi, and the Central Electrochemical Research Institute (C.S.I.R.),Dr. S.H. Purohit presented a paper on "Physico-Chemical Studies in Metal CitrateComplexes".
Physico-Chemical Studies in Metal Citrate Complexes - Abstract
The stability constants of the Citrate Complexes of Copper (II), Lead(II)and Cadmium(II) metals have been determined by direct potentiometry using amalgamelectrodes; as well as, by direct polarography using DME. the investigations have beencarried out at 30 degrees Celsius, 40 degrees Celsius, and 50 degrees Celsius, in aperchlorate medium at zonic strength µ = 2 and at pH = 4.8. The valuesof the stability constants obtained by the 2 independent techniques, show good agreement.The enthalpy changes accompanying the complex formation reactions were evaluated using VanHoff's equation. The investigations show that under the experimental conditions of pH,Citric acid as a monodentate ligand with Cu (II), Pb(II) and Cd(II) metal ions formingmono-, bis-, tris-, and tetra-coordinated complexes.
