H2S is a gas.It smells like rotten eggs.
Add an acid to Na2S.It will emit H2S.
H2S is a polar compound.It is not ionic.
The pH of a solution containing H2S would be acidic, as H2S is a weak acid. The exact pH value would depend on the concentration of H2S in the solution.
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
The formula for hydrosulfuric acid is H2S.
It is known as hydrosulfuric acid. Not to be confused with sulfuric acid which is H2SO4
Add Na2S or K2S to an acid.It will give out H2S.
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.
Dihydrogen sulfide H2S is a diprotic weak acid.
In the given reaction, the hydrogen sulfide (H2S) is the element that gets oxidized. The sulfur in H2S changes from a -2 oxidation state to 0 in sulfur dioxide (SO2), indicating oxidation.
The balanced equation for the reaction between iron(II) sulfide (FeS), hydrochloric acid (HCl), and hydrogen sulfide (H2S) is: FeS + 2HCl + H2S --> FeCl2 + H2S
