Add an acid to Na2S.It will emit H2S.
Add Na2S or K2S to an acid.It will give out H2S.
H and O have much electro negativity difference.H and S do not have much difference to make H bonds.
Hydrogen sulfide (H2S) in aqueous solutions can have a foul odor, is highly flammable, and can be toxic if inhaled. It can also react with metals to form corrosive compounds. Exposure to high concentrations of H2S can lead to respiratory issues, eye irritation, and even death. It is important to handle and store H2S solutions carefully to prevent accidents and ensure safety.
is a colourless gas that we breath. is in the air and has no colour
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.
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 is a gas.It smells like rotten eggs.
H2S do not have bleaching properties.So it do not discolor
The formula for hydrosulfuric acid is H2S.
