The group of four basic radicals, `CO^(2+)` `Nl^(2+)` `Mn^(2+)` and `Żn^(2+)` have group reagent hydrogen sulphide in presence of NH.OH. These radicals are precipitated as sulphides which are insoluble in `NH_(4)OH`. Addition of HS increases the ionization of `NH_4`OH due to reaction of OH and H lon.
`NH_4OHharrNH_(4) + OH`
`H_2S hArr2H+S^(2-)`
Salt (A) of above group cations having black colour treated with above reagent and produced compound (B), (B) on treatment with HCl and KCIO, again converted into (A) with the evolution of HS gas. (A) again treated with KCN gives a buff coloured ppt. (C) which dissolved in excess KCN and produced (D)
