Comparing Ammonium Sulfate to Ammonium Bisulfate
I would like to confirm a point you made. From your recollection for about a week on WIKIPEDIA the value for the boiling point of Ammonium Sulfate was substantially different than what is now posted on that site. I just want to make sure I correctly understand your post.

I read that ammonium sulfate decomposes at 212 (strange same temp water boils...) to I guess ammonium bisulfate. I would suspect that a scent of ammonia would emminate from the heated solution if that happens?
First of all:

Reactions
Ammonium sulfate decomposes upon heating above 250 °C, first forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water.[13]
from Wikipedia: https://en.wikipedia.org/wiki/Ammonium_sulfate#Reactions
And I'm sure they mean dry, since a water solution can't become hotter than its boiling point. So, decomposition with gentle heat shouldn't be a problem.

Thanks for the reply. I know I saw the 100 deg C on the page for about a week. The first time I reviewed it I saw what is there now with the 450 deg F range. I verified it probably 10 times as I was really confused. I may have a saved PDF of the page I will look for.
On another note, there are a number of references to the 100C temp as well.
Anyway, is there a good source for finding elements and compounds properties like those listed on wiki? I'd like to find something that I can check numbers against so things like this don't happen.
