Rants, fangirling, and other randomness not recommended by 4 out of 5 dentists. THIS JOURNAL IS NOW CLOSED. 6th-Jun-2004 05:22 pm (UTC). Nya Did you wipe your friends list and so I have to comment to be added again, or am I already there? 6th-Jun-2004 05:38 pm (UTC). I wouldn't do something like that. I didn't delete anyone! 7th-Jun-2004 07:32 am (UTC). I have been loaded with work from school so I tend to not reply that much. So you can take me off if you want. 7th-Jun-2004 12:55 pm (UTC). 20th-Aug-2004...

Buffers: chemistree
http://chemistree.livejournal.com/27668.html
A student dissolves 10.86 g of crystalline sodium acetate trihydrate (CH3COONa 3H2O) in a little water, adds 4.00 g of glacial (100%) acetic acid, and then distilled water to. Make the total volume 500 mL. Calculate the molar concentration of the buffer and its pH. My work so far. So for the trihydrate: moles = 0.092776mol. Acetic acid - 0.066608mol. But now I don't know what to do. :( Any pointers? Post a new comment. We will log you in after post. We will log you in after post. Post a new comment.

Nitrate precipitation: chemistree
http://chemistree.livejournal.com/28210.html
I am a chemistry teacher, and am stumped on a lab I am trying to develop. I'd like to create a lab that will test for nitrates without the use of store-bought indicators. Ideally, and assuming it works, I would like to use a solution to test for nitrates. There are those fish tank and spa tester kits that test for nitrates, but I want the kids to really have to see the chemicals involved in the test. I cannot figure out how to get the nitrate to precipitate out. Post a new comment. Post a new comment.
