Unlike most gas solubilities, the solubility of H 2 S in liquid sulfur has been shown to increase (non-linearly) with an increase in temperature. … This study reports the experimental solubility data for T = 120, 150 and 155 C and p H 2 S = 0.4 56 kPa .
WebHydrogen sulfide (CAS 7783-06-4)is a poisonous gas with a characteristic odour of rotten eggs and is water soluble to 4 g/L at 20°C. It is commonly found as an anaerobic degradation product of chemicals containing sulfur, such as in natural sediments, and is found in industrial wastes and landfill leachates. Web8 feb. 2024 · 5.1 Sulfide ion is found in ground waters and wastewater, causing odor and corrosion problems. If acidified, these waters can release hydrogen sulfide, which is extremely toxic even at low levels. This test method provides a means for interference-free measurement of free sulfide ion.
