Observe the following reaction: [Ne(en)_(3)](NO_(3))_(2)+S_(2)O_(3)^(2

1.	Observe the following reaction: [Ne(en)_(3)](NO_(3))_(2)+S_(2)O_(3)^(2-)(aq) overset("Slightly")underset("alk.medium")rarr'Y' (darr) violet ppt. Among the following, how many compound decompose the nickel ethylenediamine nitrate reagent with the precipitation of NiS, in the above test. Na_(2)SO_(3),Na_(2)SO_(4),Na_(2)S_(2)O_(3),Na_(2)S_(4)O_(6),H_(2)S, (NH_(4))_(2)S,NaSCN
Answer» SOLUTION :`H_(2)S,(HN_(4))_(2)S`
