Complexes and preipitates of nickel (II) are formed by adding ammonium hydroxide, ethylenediamine, and dimethylglyoxime to dilute solutions of Ni2+ in beakers. Cyanide salts and solutions are ...

Ammonia is added to solutions of cobalt, nickel, and copper 2+ cations. First formation of the hydroxide precipitate is seen, then of the ammonia complex. Pour 0.1M solutions of Cu2+, Co2+, and Ni2+ ...

Researchers have developed a new method for recycling spent battery materials that can extract 99.99% of the lithium from ...

This breaks up the NCM layers, releasing the lithium, nickel, cobalt, and manganese ions they contain into the solution. In the second trick, these ions are "trapped" in complexes by the glycine.
