Enter the ions formed when (nh4)2s dissolves in water.

The ions formed are NH4(+) and S(2-)

The dissolution reaction of (NH4) 2S in water is as follows:

(NH4) 2S ==> 2 NH4 (+) + S (2-).

Ammonium sulfide is the ammonium salt of hydrogen sulfide. It has the formula (NH4) 2S and belongs to the sulfide family.

It is a relatively unstable compound (crystals decomposing at -18 ° C, but exists and is more stable in aqueous solution.) With a pKa exceeding 15, the hydrosulfide ion cannot be significantly deprotonated by ammonia. Thus, such solutions consist mainly of a mixture of ammonia and hydrosulphide of ammonium, it has a smell, close to that of hydrogen sulfide, and its aqueous solutions can be precisely by emitting H2S.

Dissociation of ions is a process in which substances when dissolve into water will break into ions. In the compound Ammonium Sulfide or (NH)SOthe ions dissociated will be:

The compound ammonium sulfide is the salt of hydrogen sulfide. It is an unstable compound, which dissociates upon heating at 250-degree celcius. The pKa value exceeds 15, therefore, sulphate cannot be deprotonated by ammonia.

Thus, the mixture comprises ammonia and sulphate of ammonium. The compound is characterised by pungent smell.
