At equilibrium, the concentration of H2S(aq) remains constant.
This is because at equilibrium, the forward and reverse reactions occur at the same rate, resulting in a constant concentration of H2S(aq).
Hydrogen sulfide, H2S(g), is a colourless, toxic, flammable gas. Its main use is in the qualitative inorganic analysis of certain metal ions. Hydrogen sulfide gas ionizes in water as shown below:
H2S(aq) + H2O (l) → H3O+(aq) + HS–(aq)
