Problem 2.12

When 1.3584 g of sodium acetate trihydrate was mixed into 100.0 cm3 of 0.2000 m HCl(aq) at 25C in a solution calorimeter, its temperature fell by 0.397C on account of the reaction: H3O+(aq) + NaCH3CO2 3 H2O(s) Na+(aq) + CH3COOH(aq) + 4 H2O(l). The heat capacity of the calorimeter is 91.0 J K1 and the heat capacity density of the acid solution is 4.144 J K1 cm3. Determine the standard enthalpy of formation of the aqueous sodium cation. The standard enthalpy of formation of sodium acetate trihydrate is 1064 kJ mol1.
