Homework Problem 16.29 Part D

Postby Griffin Schneider 1I » Mon Dec 01, 2014 9:51 pm

This part asks us to write the formula for sodium bisoxalato(diaqua)ferrate (III) and I have two questions about this.

Why is the bisoxalato written before diaqua? Shouldn't they be ordered alphabetically without regard for the prefixes?

Also, the answer to the question is Na[Fe(OH2)2(C2O4)2]. Why is the diaqua written first here? Shouldn't the bisoxalato be written first because it is an anion while the diaqua is a neutral molecule?

I am not exactly sure about your first question (it may follow the same "rule" that I mentioned for your second question).
Second Question: The neutral molecule is always written first and then the anion. If there is more than 1 anion (ionic) list it in order of atomic number.

Lavelle recently posted in this same category with his own thread that states the exact opposite.

Which form is correct?

Lavelle's post is from 2011. They (scientist? or someone) updated the rule so instead of having the anionic compound first it would be the neutral compound and then the anionic compound.

So it is always the neutral atom first got it thank you! Also, for this same question why would there be a bis there?

The "bis" is there because there are two oxalate ions in the compound.
