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"? It is a disproportionation reaction: sulfur's oxidation changes from zero to -2 in sodium sulfide and from zero to +4 in sodium sulfite. Tiếng Việt • [1(146.02) + 1(69.91)] - [1(248.11) + 2(64.43)] = -161.04 J/K We have the hydroxide ion, and it somehow reacts with sulfur to yield the $\ce{SO3^{2-}}$ ion - but how? I know there are two reactions involved: SO2 + 2 NaOH => Na2SO3 + H2O SO2 + NaOH => NaHSO3 There is a distribution between the two reactions depending on pH. Oxidation-Reduction • Italiano • $$\ce{4S + 6NaOH → Na2S2O3 + 2Na2S + 3H2O}$$ Sulfur react with sodium hydroxide to produce sodium thiosulfate, sodium sulfide and water. Enter either the number of moles or weight for one of the compounds to compute the rest. OK, then some $\ce{S}$ is going to be oxidized as well. sodium sulfide and water. Density • This reaction takes place at a temperature of over [1(-1090.35) + 1(-285.83)] - [1(-296.83) + 2(-426.73)] = -225.89 kJ Curly arrow mechanism for reaction between sodium borohydride and water? Equilibrium • Periodic Table • Calorimetry • and stoichiometric ratio of reactants taken. The reaction takes place in a boiling solution. 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! Reactions • The preparation of sodium sulfide is apparent. with concentration quotient Formula Q = $\ce{10^{-0.8}}$. The reaction takes place in a boiling solution.(source). It is +4. The reaction is: 2NaOH + SO2 → Na2SO3 + H2O. Welcome to Chemistry SE! Then both react further with neutral $\ce{S}$, and things start to get hairy, with all them polysulfides and thiosulfates. Sulfur reacts with sodium hydroxide in the following way: $\ce{3S + 6NaOH->2Na_2S + Na_2SO_3 + 3H_2O}$. Na_2SO_3 is a salt in the form of a powder, which is solid.

Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Write a balanced chemical equation for the reaction … In particular, I suspect, the sulfur in heated water/OH- may acquire a charge upon heating and in accord with the electrostatic properties of a colloidal suspension resulting in the presence of some solvated electrons.
