This solution is. of great importance in the laboratory, and is prepared by passing the gas from the generating flask A, fig. 51, through a wash-bottle, B, and then into a beaker or other vessel containing water, until the water is saturated with the gas. 220. Properties.--Sulphuretted hydrogen is a colourless gas, having a characteristic odour of rotten eggs. The solution in water has a corresponding odour, and sweetish taste. It is inflammable, and a non-supporter of combustion. With excess of oxygen, sulphur dioxide and water are produced by the burning of this gas, according to the equation:--2SH2 + 302 = 2S02 + 2H20. Sulphuretted Oxygen. Sulphur Water, hydrogen. dioxide. On holding above the flame a rod dipped in ammonia the sulphur dioxide forms a solid compound, named ammonium sulphite. The fumes of this body are evidence of the presence of sulphur dioxide--S02 + 2NH4HO = (NH4),S03 + H20. Sulphur Ammonium Ammonium Water, dioxide. hydrate. sulphite. Sulphuretted hydrogen produces no fumes with ammonia. More conclusive evidence of the presence of sulphur dioxide as one of the pioducts of combustion is afforded by holding the nose above the flame, when its characteristic odour is observed. When the supply of air is limited, as when the gas burns in a jar, the sulphur is in great part deposited, the hydrogen only being burned. 2SH2 + 02 = S, + 2H,0. Sulphuretted Oxygen. Sulphur. Water, hydrogen. Under a pressure of seventeen atmospheres, sulphuretted hydrogen condenses to a colourless liquid, whose boiling and freezing points are respectively--62 and--86 C. Water at ordinary temperatures dissolves about 3-25 volumes of the ga...
