Add an acid to Na2S.It will emit H2S.
When sulfur and hydrogen are combined, they can form hydrogen sulfide (H2S), which is a colorless gas with a characteristic rotten egg odor.
The formula for dihydrogen sulfide, or just hydrogen sulfide, is H2S. A pair of hydrogen atoms are bonded to a sulfur atom to make up this toxic compound. A link can be found below for more information.
H2S is a polar compound.It is not ionic.
Hydrosulfuric acid is H2S. H2S (aq) (H2SO4 is sulfuric acid). The acids with "hydro" at the start of their names are all derived from dissolved gases, e.g. hydrochloric acid is aqueous hydrogen chloride, hydrocyanic acid is aqueous hydrogen cyanide etc.
H2S do not have bleaching properties.So it do not discolor
H2S is a gas.It smells like rotten eggs.
The formula for hydrosulfuric acid is H2S.
H2S = hydrogen sulphide
It is known as hydrosulfuric acid. Not to be confused with sulfuric acid which is H2SO4
do the lab
To find the number of moles of hydrogen sulfide, divide the given mass by the molar mass of hydrogen sulfide. The molar mass of hydrogen sulfide is approximately 34.08 g/mol. Thus, 64.6 g / 34.08 g/mol = 1.9 moles of hydrogen sulfide in the sample.
