The name of complex ion, [Fe(CN)6]3- is 

  • hexacyanoiron (III) ion

  • hexacyanitoferrate (III) ion

  • tricyanoferrate (III) ion

  • hexacyanidoferrate (III) ion

Solution

D.

hexacyanidoferrate (III) ion

When complex- ions is an anion, the name of the metal ends with the suffix -ate along with its oxidation number in the complex- ion.
[Fe(CN)6]3- = Hexacyanidoferrate (III) ion
