In this way, you can determine which element is oxidized (loses electrons) and which element is reduced (gains e ...

... 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 ...
