In basic medium the amount of Ni^(2+) in a solution can be estimated with the dimethylglyoxime reagent. The correct statement (s) about the reaction and the product is (are)

Answer»

in ammoniacal SOLUTION `Ni^(2+)` salts give cherry RED precipitate of nickel (II) dimethylglyoximate
two dimethylglyoxiamte units are bound to one `Ni^(2+)`
in the complex dimethylglyoximate units are hydrogen bonded to each other
each dimethylglyoximate unit forms a SIX MEMBERED chelate ring wilth `Ni^(2+)`
