Question 4.4: The enthalpy of solution for the reaction Na2SO4(s)→2 Na^+(a...

The enthalpy of solution for the reaction

Na_{2}SO_{4}\left( s \right)\overset{H_{2}O\left( l \right)}{\longrightarrow } 2 Na^{+}\left( aq \right)+SO^{2-}_{4}\left( aq \right)

 

is determined in a constant pressure calorimeter. The calorimeter constant was determined to be 342.5  J  K^{-1}.When 1.423 g of Na_{2}SO_{4} is dissolved in 100.34 g of H_{2}O\left( l \right),\Delta T=0.031  K. Calculate \Delta H°_{solution} for Na_{2}SO_{4} from these data. Compare your result with that calculated using the standard enthalpies of formation in Table 4.1 (Appendix A, Data Tables) and in Chapter 10 in Table 10.1.
