Thanks for contributing an answer to Chemistry Stack Exchange! We use cookies to improve your website experience. The reactions may proceed in absorbed water on the surface of a reactor and a fiber filter. They consist of ammonolysis of SO2, followed by auto-redox disproportionation of SIV into a range of oxidation states. But $\ce{S4N4}$ is a relatively common and well known one. Okay, I was only worried, even though $\ce{S4N4}$ may be a common and well-known compound, if the reaction conditions allow for its formation or not? Abstract The reaction of sulfur dioxide with excess ammonia was studied during warm-up of rare gas matrices and in sealed pressure tubes containing various isotropic species. If you really mean sulfur plus ammonia, then the solid cannot contain oxygen which is not present in the system. Key Words : sulfur dioxide, ammonia, reaction, reaction temperature, relative humid ity 1. I wish to ask how "we would expect" that only $\ce{S4N4}$ would be formed, and not any other compound (like $\ce{S5N5}$)? By closing this message, you are consenting to our use of cookies. Which compound results in the following products when mixed with AgNO3 and Chlorinated water. Surely, $\ce{H2S}$ gas will evolve. Have any other US presidents used that tiny table? Raman spectra show the presence of sulfate, dithionate, thiosulfate, and the polythionates.

What would be a proper way to retract emails sent to professors asking for help? How to separate and analyse a sample of cations of alkaline and earth alkaline cations and ammonium? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Journal of Industrial and Engineering Chemistry 2012 , … Why should I acidify twice in the procedure for qualitative analysis of chloride anions? Is it ammonium sulphide or ammonium sulphite? How to make my own professional book step-by-step( there is a course or a book that I didn't find? hydrogen sulfite. In some tubes with NH3:SO2 <7 a spontaneous reaction occurs after 1 ½ to 2 years and the colorless or pale yellow solution turns a brilliant violet signalling the decomposition of thiosulfate and polythionate into elemental sulfur which reacts with the liquid ammonia yielding negatively charged polysulfide radical ions. There could be several products, but we would expect some sort of sulfur-nitrogen compound such as $\ce{S4N4}$, a reaction referred to here. The reaction of sulfur dioxide with excess ammonia was studied during warm-up of rare gas matrices and in sealed pressure tubes containing various isotropic species. I don't think this question has a simple answer. cold, pure, not dissolved in water) ammonia, then only one of your two suggestions is possible. Shouldn't some stars behave as black holes? In the matrix experiments six IR bands belonging to ammonium thionylimide, NH4: NSO, were observed in the temperature range between 40°K and 90°K. Why did my iron nails not dissolve in hydrochloric acid? In sealed tubes containing liquid ammonia at room temperature several step-wise reactions can be followed. The results show that the reactions are very fast and the products are mixtures of various types of ammonium−sulfites with (NH4)2SO3 as the main component. Why do people call an n-sided die a "d-n"? ), Drawing a RegionPlot from a Table of Values, Old Budrys(?) MathJax reference. Dirac Notation and Coordinate transformation of a function. What about the solid? Production of elemental sulfur and ammonium thiosulfate by the oxidation of H2S containing water vapor and ammonia over V/Zr-PILC catalysts. It only takes a minute to sign up. MAINTENANCE WARNING: Possible downtime early morning Dec 2/4/9 UTC (8:30PM…, “Question closed” notifications experiment results and graduation, finding cation of unknown salt in solution from precipitate. In the matrix experiments six IR bands belonging to ammonium thionylimide, NH 4: NSO, were observed in the temperature range between 40°K and 90°K. Asking for help, clarification, or responding to other answers. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. If you’re sure that you only have sulphur and liquid (i.e. Register to receive personalised research and resources by email, THE REACTIONS OF SULFUR DIOXIDE WITH EXCESS AMMONIA, Department of Chemistry , University of Washington , Seattle, WA, 98195, USA, Department of Chemistry , University of Washington , Seattle, WA, 98195, USA ; Materials and Molecular Research Division Lawrence Berkeley Laboratory , University of California , Berkeley, CA, 94720, USA ; University of Washington, Department of Chemistry , University of Washington , Seattle, WA, 98195, USA ; Materials and Molecular Research Division Lawrence Berkeley Laboratory , University of California , Berkeley, CA, 94720, USA ; University of California, Berkeley, /doi/pdf/10.1080/03086648008078203?needAccess=true, Phosphorus and Sulfur and the Related Elements. Is it against the rules to see someone's exam answers after the exam? This paper's first page (all I can see without a subscription) indicates that sulfur can dissolve in liquid ammonia, producing hydrogen sulfide (as the question correctly states) and... complicated stuff: S7N-, which disproportionates into S4N- and "an" ammonium polysulfide (maybe (NH4)2S6, maybe another composition). By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. There are multiple sulfur-nitrogen compounds, really. I don't think this question has a simple answer. Does liquid ammonia react with hydrogen gas? “…presume not God to scan” – what does it mean? The paper's first page also refers to the system's light sensitivity, so if you don't keep it in the dark, you may get different products. end-of-world/alien invasion of NYC story, I mistakenly revealed name of new company to HR of current company.
