Vedclass · Answer

(D) The reaction between $Ni^{2+}$ and dimethyl glyoxime $(DMG)$ forms a nickel dimethylglyoximate complex,which is a bright red precipitate.This reaction is typically performed in an ammoniacal medium,which provides an alkaline $pH$ range of $9-11$.In this $pH$ range,the deprotonation of the $DMG$ ligand occurs,allowing it to coordinate effectively with the $Ni^{2+}$ ion.

Dimethyl glyoxime gives a red precipitate with $Ni^{2+}$,which is used for its detection. To get this precipitate readily,the best $pH$ range is
