Abstract
The heats of formation of oxalic acid and sodium, potassium oxalates, and lithium oxalates were related by solution calorimetry to the heat of formation of (cooh)2.2H2o, a value believed to be reliable as reported in the literature. The following heats of formation were determined: (cooh)2(a), -198.1+-0.1; (Cooh)2(b), - 197.8+-0.1; Li2c2o4, -328.7+-0.4; Na2c2o4, -316.2+-0.1; K2c2o4, - 321.9+-0.2; and k2c2o4.H2o, -393.5+-0.2 Kcal/mole. The heat of the crystalline transformation (cooh)2(a) -> (cooh)2(b) was determined to be 0.30+-0.02 Kcal/mole at 298.15 Deg. K.
