Nessler's reagent is

Nesslers reagent is used to detect trace amounts of ammonia. Its formula is

Ammonia (NH_(3)) when treated with 'Nessler's reagent in the presence of an alkali gives a brown precipitate of

Compound A on hydrolysis gives gaseous compound B and alkaline solution. When B reacts with Nessler's reagent it gives brown ppt. when 'B' reacts with H_(2)[PtCI_(6)] it gives yellow ppt of C. Hybridised state of central atom of the ionisation sphere of compound C is:

In Nessler's reagents, the ion present is :
