... Q. 73. Why, H2S gas passed in presence of NH4OH? Ans. When H2S gas is passed in alkaline medium or in presence of NH4OH, the H+ ions from the dissociation of H2S gas combine with hydroxyl ions (OH-) from the dissociation of NH4OH to from nearly unionised H2O. The removal of H+ ions from the solutio ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
