7th edition 9.C1

Postby Elena Maneffa 1E » Wed Dec 05, 2018 9:19 pm

The question is:

Name each of the following complex ions and identify the oxidation number of the metal
a. [Fe(CN)6]^4-

b. [Co(NH3)6]^3+

c. [Co(CN)5(OH)2]^2-

d. [Co(NH3)5(SO4)]^+


When do you know when to write cobalt vs cobaltate or iron vs ferrate?

Thanks :)

If the complex has a total negative charge, add -ate at the end of the metal name. If the complex has a negative charge while the metal name comes from Latin, use the Latin stem.

For example:
Fe: -ferrate

You use cobaltate and ferrate if the complex is an anion and cobalt and iron if the complex is a cation.
