potassium acetate

[witchdoc]

I am looking for thermodynamic property info for potassium acetate (both crystalline and aqueous). In particular, I need the enthalpy of formation.

In my Perry I found:
KC2H3O2:
m.w.=98,15;
d=1,57(@ 25 degC)
melt.p.=292 degC
solub=(g/100mlwater)253 (@ 20 degC)
492 (@ 62 degC)
standard heat of formation c. @25degC=-173 kcal/mol
standard heat of formation (aq 400)@25degC=-177,38 kcal/mol
free energy of formation (@25 deg C)=-156,73 kcal/mol
