When 1.3584g of sodium acetate trihydrate was mixed into 100.0cm3 of 0.2000 M HCl (aq) at 25 0Cin a solution calorimeter, its temperature fell by 0.3970C on accoun of the reaction:
H3O+ (aq) +NaCH3CO2 . 3H2O (s) -->Na+ (aq) + CH3COOH (aq) + 4 H2O(l).
The heat capacity of the calorimeter is 91.0 J/K and the heatcapacity density of the acid solution is 4.144J/Kcm. Determine thestandard emthalpy of formation of the aqueous sodium cation. Thestandard enthalpy of formation of sodium acetate trihydrate is-1064kJ/mol.
