Dmg reaction with nickel4/12/2023 The detection of Ni2 is based on the appearance of a unique infrared absorption peak at 1572 cm(-1) that corresponds to the CN stretching mode in the nickel dimethylglyoximate, Ni(DMG)2, complex. Nafion film embedded with dimethylglyoxime (DMG) probe molecules. ![]() Ni 2+ (aq) ions reacts with concentrated Cl-ions in the presence of acids to give tetrachloronickel(II) ion / NiCl 4 2-, a yellow brown solution. Nickel detection was accomplished on a silicon ATR parallelogram crystal uniformly coated by a ca. Ni 2+ (aq) ions reacts with concentrated Cl-ions in the presence of ethanol medium to give tetrachloronickel(II) ion / NiCl 4 2-, a blue colour solution.
