Re: latin names

When the coordination compound has a negative charge we would usually add the suffix -ate to the Lewis Acid, but for iron we would change it to ferrate

Re: How to determine whether a molecule is an acid or a base

because it has one lone pair its most likely going to donate it and that what considers a base.
