I have two related questions about analysis.
1) What is the acceptable range? I was brought up on + 0.4%.
2) Does anyone have an official source for the 'acceptable' range? I looked at the guide for authors for Inorg. Chem. and couldn't find it. I did a little more digging and still haven't found it. Maybe I am just not looking in the right places. Maybe it is a legend that just gets passed on from generation to generation. I don't know. I want to students to consider this in lab for one of my courses, but I want something more official than "this is the way it is". There has to be something out there and I am just too dumb to find it. Any thoughts are appreciated.
