The IUPAC name of [Co(H_2NCH_2CH_2NH_2)_2 (NO_2)NO_5 is bis(enthane-1,2-diamine) dinitrito-N-cobalt(III) nitrate.It follows the following rules that. (a)Cation is named first followed by anion. (b) Ligands are named in an alphabetical order before the name of the central atom/ion. ( c)Name of anionic ligands end in "o" (ex.chlorido) those of neutral (and if cation) ligands are the same except aqua for H_2O , ammine for NH_3 etc. (d)Prefixes mono,di,tri,etc.are used to indicate the number of individual ligand.When the name of the ligands include a numerical prefix, then terms bis, tris, tetrakis are used. (e)Oxidation state of the metal is indicated by Roman numeral in parenthesis. (f) For cationic and neutral complexes, the metal is named same as the element and for anionic complex, the name of metal ends with suffix-ate.For some metals, the Latin names are used in the complex anions , e.g., ferrate for Fe, argentate for silver etc. The correct IUPAC name of the coordination compound [Pt(NH_3)_2Cl(NH_2CH_3)] is :

Metallic gold frequently is found in aluminosilicate rocks and it is finely dispersed among other minerals. It may be extracted by treating the crushed rock with aerated sodium cyanide solution. During this process metallic gold is slowly converted t [Au(CN)_(2)]^(-) , which is soluble in water. After equlibrium has been reached, the aqueous phase is pumped off and the metallic gold is recovered from it by reacting the gold complex with zinc, which is converted to [Zn(CN)_(4)]^(2-) , Gold in nature is frequently alloyed with silver is also oxidised by aerated sodium cyanide solution. The correct ionic reaction for the process is//are:
