  1. No. I have been given a project to determine the iron content in Sulphuric acid. And i'm searching for a replacement for Br2.
  2. What is the role of Bromin in determination of ferric ions in battery acid using comlexation of ferric ions with thiocyanate????
  3. It is not the case always..... the slag contains 6% Lead ad 60% Iorn. I'm searching a method to extract lead from this composition....This is one of my assingment for my industrial training...I went through an article pulished by a Journal, ( Journal of Hazardous Materials). but it provides a qualitative method.... I'm interested in a quantitative metohd which can be applied in an industrial base...
  4. come on SFN......things seem to be more easy and attractive now......

      Glad to hear it. Let me know if you have comments or suggestions.

  5. can any one please sugest a method to extract lead from slag!!!!!
  6. You better check in Advanced Inorganic Chemistry by Cotton and Wilkinson to find a better answer for it.....
  7. Can anyone please help me to find a proper book (online) which gives a detailed description about the TANABE SUGANO diagrams????
  8. I don't think there exist anything called ".semi safe to breathe." Every thing has some hazardous effect on us in different potentials... I think better avoid inhaling anything that comes out of the reaction vessel.....
  9. What is the modification of WADE'S rule upon deriving the structure of metal cluster boranes???
  10. Can anyone please tell me what is the largest class of Silicates??
  11. Yes, but i was not sure with it. Thanx a lot.
  12. I think you will find a good answer in the Atkins'Physical Chemistry by P.Atkins and Julio De Paula. Merged post follows: Consecutive posts merged Also you can use this link http://en.wikipedia.org/wiki/Michaelis%E2%80%93Menten_kinetics:-)
  13. It's simple, it is the acetate anion, [CH3COO]−, is a carboxylate. It is the conjugate base of acetic acid. CH3COOH ⇌ CH3COO− + H+
  14. Thank you for your attempt... but i really wanted to know about how the reaction mechanism goes... I know it is a Diels Alder reaction and also that there is a Carbon monoxide evolution... All i want to know is this is correct or are there any other possibilities???
  15. can any one please tell me how does tetraphenyldihydrophthalic anhydride is formed from tetraphenylcyclopentadienone and maleic anhydride in the presence of bromobenzene?? Is it a kind of a Diels Alder Reaction?? And what is the role of bromobenzene??
