Hydrogen Sulfide and Sulfur Dioxide Reaction
2H2S + SO2 --> 2H2O + 3S
But under what conditions?
I generated these two gasses in separate test tubes adding dilute HCl to FeS and Na2S2O3. I could definitely smell both from near the test tubes. I
brought the test tubes together, under a bright light so I could see any precipitating S in the air. I was thinking this would work similar to the
reaction between HCl and NH3 to produce a cloud. But no cloud whatsoever.
I'm guessing maybe both gasses have to be dissolved in water for this to work?

Thermodynamics says it should work
| Code: | ΔH -234.4965 kJ/mol
ΔS -424.0484 J mol/K
temp 293.15 Kelvin
20 Celsius
ΔG = ΔH - TΔS
ΔG -110.19 kJ/mol
ΔG=0 T= 552.99 K 279.84 C |
The colder the better, but that would go against kinetics.
Maybe dissolve the gasses in a solvent?
