Dimethyl glyoxime is a specific reagent for the _________metal ion?
Al
Ni
Fe
Cu
Dimethyl glyoxime is an extraordinarily sensitive reagent for nickel. many derivatives of dimethyl glyoxime have been synthesized and proposed Although comment use as a reagent specific to nickel, Dimethyl glyoxime actually allows the detection of other metal ions. When dimethyl glyoxime is added to a solution along with ammonia hydroxide, the formation of a bright red precipitate indicates the presence of Ni2+ ions in the solution. this is due to the formation of nickel dimethyl glyoxime complex.
Therefore the correct answer is Ni.
