Chemistry of Metal Ions:-
Nickel: Nickel has been determined using dimethyl glyoxime method.
Copper: Copper ions from brown colour with sodium diethyldithiocarbamate solution.
Iron: The orange red colour formed by ferrous iron with 1, 10 Ortho-phenanthroline is the basis of determination of iron.
Phosphorus: Phosphorus reacts with potassium antimony tartrate and ammonium molybdate solution to form phosphoantimonyl molydate complex which on reduction with ascorbic acid forms blue colour.
