Hydrogen sulphide is a colourless gas and, being a weak acid, is highly soluble in water.

In case of production the downstream production plants must also be tailored to the specific properties of sour gas and associated challenges: a cleaning plant first of all removes the hydrogen sulphide from the gas using the OASE gas treatment technology developed by Wintershall's parent company, BASF.
The calculations suggest that there should be lower flame speed and pressure build-up in propagating hydrogen sulphide deflagration than natural gas mixtures.
However, there was some stagnant water at the bottom and hydrogen sulphide can build up in stagnant, polluted water.
"Data available so far strongly suggest that hydrogen sulphide may become the next potent agent for preventing and ameliorating the symptoms of ageing and age-associated diseases," Jiang said in a statement, adding that people may one day take hydrogen sulphide-rich food or supplements to slow ageing.
Hydrogen sulphide is known to be a deceptive gas, because although it is very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late.
The filter has bacteria that feed on the hydrogen sulphide. With the hydrogen sulphide taken up by these bacteria, what is released is air that is odourless, he added.
So he tried again in 1958 and took the crucial step of adding hydrogen sulphide - a toxic gas released by volcanoes - to the mix.
Small amounts of hydrogen sulphide - a toxic gas generated by bacteria living in the human gut - are responsible for the foul odour of flatulence.
