Understanding Compound Suffixes: -ate, -ous, -ic, & More

[Xishan]

What does this -ate suffix with compounds mean? Can anybody tell about other suffixes like -ous -ic etc as well.

Thanks...

well, it depends, but in organic & biochemistry it means that you have a stable ion of a carboxylic acid at a particular pH.

for example, pyruvic acid:

$$CH_3COCOOH$$

is the carboxylic acid. but at pH > 3, most of it will be found in the deprotonated form:

$$CH_3COCOO^-$$

this is called "pyruvate". the same convention holds for other carboxylic acids.

if you are talking about general or inorganic chemistry, then "-ate" is used to designate oxidation states of polyatomic ions, as Dr. Mark's link indicates.

Thanks, Dr. Marks! that's all I was looking for
