Question

Given below are two statements :

Statement I : The identification of Ni²⁺ is carried out by dimethyl glyoxime in the presence of NH₄OH.

Statement II : The dimethyl glyoxime is a bidentate neutral ligand.

In the light of the above statements, choose the correct answer from the options given below :

Accepted Answer

Option D. Statement I is true. Dimethyl glyoxime (DMG) is a chelating reagent commonly used for the identification of Ni²⁺ ions in aqueous solution. In the presence of ammonium hydroxide (NH₄OH), Ni²⁺ reacts with dimethyl glyoxime to form a deep red-colored complex, which can be used to confirm the presence of Ni²⁺ ions.
