Theromodynamics Lab
« on: November 13, 2009, 10:30:01 AM »
I'm in the middle of a thermodynamics lab where I have to measure and compare the expiramental/theoretical change in temperature for the reaction between sodium carbonate and citric acid. I've been looking for a while now and I can't find the heat of formation of sodium citrate. (For my theoretical value) I've found it for both sodium carbonate and citric acid, but I've looked everywhere and yet I can't find it for sodium citrate.

So does anyone know the heat of formation of sodium citrate?

Anybody?

All I'm asking for is the heat of formation for Sodium Citrate.

Ask librarian for help.

What, I'm assuming you mean the librarian at my library, well I've already checked and I can't find sodium citrate in any book.

No idea what school you are in, but librarians may have access to other resources.
