Sulfur reacts with sodium hydroxide in the following way: $\ce{3S + 6NaOH->2Na_2S + Na_2SO_3 + 3H_2O}$. [1(146.02) + 1(69.91)] - [1(248.11) + 2(64.43)] = -161.04 J/K In the current text, the reaction equilibrium may be moved to the right with the consumption of formed radicals with say sulfur/sulfur compounds. The reaction is: 2NaOH + SO2 → Na2SO3 + H2O. Home Reactions Blog. Atomic History • Depending on that, you will get various products in each case if you slightly change the conditions or the ratio of sodium hydroxide to sulfur taken. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. When you compare the three equation, you can see that though stoichiometric ratio of the reactants in the 1st and 3rd equation is same, the moles of sulfur and sodium hydroxide is different and thus gives different products in each case. 4.9839806128e+031 $$\ce{Na2S2O3 ->[220-300 C] Na2SO3 + S}$$. So to balance it: SO_2 (g)+2NaOH_((s))->Na_2SO_3(s)+H_2O_((l)) SO_2 is a gas. ; Brooks/Cole: Belmont, CA, 2014; p 135. Error: equation SO2+NaOH=Na2SO4+H2O is an impossible reaction Please correct your reaction or click on one of the suggestions below: SO2 + NaOH = H2O + Na2SO3 Instructions and examples below may help to solve this problem You can always ask for help in the forum Then, the formation of sulfur related radical(s): A path to the consumption of the highly reactive and non-selective hydroxyl radical (created above) could be: One could also argue that the action of heat/light (see, for example, https://www.sciencedirect.com/science/article/pii/S1010603018309729 ) may reverse the above reaction leading to S•− radical. Next, an interaction with oxygen per a 2019 source (https://pdfs.semanticscholar.org/533e/9a0b2e5d938abc555e267f2f9b1a6a29f720.pdf ): HS•/S•− + O2 --> SO2•- (+ H+) (Source Page 7, Eq (7)), SO2•- + SO2•- --> S2O4(2-) (Same source, per comment). The reaction is: Na2SO3 + SO2 → Na2S2O5. For further reading and reference, list of sources can be found at the conclusion of each page. Measurement • If a piece of software does not specify whether it is licenced under GPL 3.0 "only" or "or-later", which variant does it "default to"? Español • Русский • Hi I'm designing a scrubber and need some help. H_2O is liquid, for obvious reasons. Alkanes • Equilibrium • disproportionation.$\ce{SO3^2-}$ reacts with $\ce{S2^2-}$ and What exactly limits the signal frequency on transmission lines? Is there a way to understand why sodium sulfite forms? Then, per Wikipedia on dithionite (see https://en.wikipedia.org/wiki/Dithionite ), notes that dithionite undergoes an acid hydrolytic disproportionation to thiosulfate and bisulfite (presence of CO2 may assist): Thanks for contributing an answer to Chemistry Stack Exchange! Reaction stoichiometry could be computed for a balanced equation. हिन्दी • Write a balanced chemical equation for the reaction … Is oniichan also used to refer to a big sister? If in the same reaction, water is present, then the reaction is different. Can someone be saved if they willingly live in sin? Unit Conversions, Afrikaans • -161.04 J/K     (decrease in entropy), From ΔGf° values: Sodium hydroxide - concentrated solution. sulfide and water. and thus one mole sulfur cancel from each side and gave reaction 3 (your reaction). Electromagnetic Radiation • SO2 + NaOH = Na2SO3 + H2O | Chemical reaction and equation Sulfur dioxide react with sodium hydroxide SO 2 + 2NaOH → Na 2 SO 3 + H 2 O [ Check the balance ] To subscribe to this RSS feed, copy and paste this URL into your RSS reader. OK, then some $\ce{S}$ is going to be oxidized as well. This process is favorable at 25°C. -177.88 kJ     (spontaneous). Enter a mass or volume in one of the boxes below.
