If H2S is 200 mg/l in vapor phase what is the concentration in water phase in mg/l
To find the concentration of H2S in the water phase, we need to understand its solubility in water. H2S is highly soluble in water and forms a weak acid known as hydrosulfuric acid.
The solubility of H2S in water depends on several factors, including temperature and pressure. At standard temperature and pressure (STP; 25 degrees Celsius and 1 atmosphere), the solubility of H2S in water is approximately 2.8 grams per liter (g/L) or 2800 mg/L.
So, if the concentration of H2S in the vapor phase is given as 200 mg/L, it indicates that the equilibrium concentration of H2S in the water phase can potentially reach 2800 mg/L at STP.
However, it's important to note that the actual concentration of H2S in the water phase can be affected by various factors, such as the specific conditions, presence of other solutes, and the kinetics of the system.
To determine the exact concentration of H2S in the water phase in a given scenario, it is advisable to conduct laboratory experiments or refer to existing experimental data or models that account for the specific conditions and parameters of interest.
