Vedclass · Answer

(D) The reagent used for the detection of $Ni^{2+}$ ions is dimethyl glyoxime $(dmg)$.In the presence of an ammonium hydroxide $(NH_4OH)$ basic medium,$Ni^{2+}$ reacts with $dmg$ to form a complex,$Ni(dmg)_2$,which appears as a brilliant red precipitate.The chemical reaction is: $Ni^{2+} + 2C_4H_8N_2O_2 \rightarrow [Ni(C_4H_7N_2O_2)_2] + 2H^+$.Thus,the correct option is $D$.
