WebScience Chemistry At 25 °C and standard pressure, a hydrogen sulfide solution can be made by bubbling H,S (g) into water; the result is a 0.11 molar solution. Since H2S (g) is more dense than air we can assume that a layer of pure H2S (g) at atmospheric pressure covers the solution. What is the value of Henry's law constant? kH= gL-latm 1. WebMeasurement of hydrogen sulfide (H2S) is a critical practice for quality control and safety purposes. Without precise quantification of H2S in a process, efficient processing of crude oil is not possible. To maintain safety when transporting crude oil and condensate, measurement of the H2S content is vitally important. incident at deadhorse part 2

WebHenry's gas law postulates that at constant temperature there is a direct proportionality of the amount of gas that can be dissolved in a given volume and type of liquid to the partial pressure of the gas in equilibrium with the solvent. The constant of proportionality is called Henry's law constant and depends on the type of gas, type of liquid and temperature.
