In the process of extraction of gold Roasted gold ore + CN^(-) + H_(2)O overset(O_(2))rarr [X] + OH^(-) [X] + Zn rarr [Y] + Au Identify the complexes [X] and [Y]

Answer»

`X = [Au(CN)_(2)]^(-), Y = [ZN(CN)_(4)]^(2-)`
`X = [Au (CN)_(4)]^(3-), Y = [Zn(CN)_(4)]^(2-)`
`X = [Au(CN)_(2)]^(-), Y = [Zn(CN)_(6)]^(4-)`
`X = [Au(CN)_(4)]^(-), Y = [Zn(CN)_(4)]^(2-)`
