HW 17.29 about the metal ion

Postby Aijun Zhang 1D » Sat Nov 25, 2017 6:00 pm

For 17.29 b and c, I noticed that the answer for b just contains "cobalt(III) ion"; however, answer for a and c is "ferrate(II) ion" and "cobaltate(III) ion". Why is cobalt in b is written as only the metal name, but cobalt in c is written as -ate form?
Thanks!

When the complex has an overall negative charge, you add the suffix -ate to the metal's name. This is the case for part b, since the anion has an -2 charge. Hope this helps! :)

I'm seeing lots of good chemistry.
