Vedclass · Answer

(D) Nessler's reagent is an alkaline solution of potassium tetraiodomercurate$(II)$,$K_2[HgI_4]$.In the presence of ammonia or ammonium salts,the active species $HgI_4^{2-}$ reacts to form a brown precipitate known as the iodide of Millon's base.The chemical reaction is:$2[HgI_4]^{2-} + NH_4^+ + 4OH^- \rightarrow NH_2Hg_2OI + 7I^- + 3H_2O$Thus,the active species involved in the detection is $[HgI_4]^{2-}$.

In Nessler's reagent for the detection of ammonia,the active species is:
