Standard enthalpy change of solution
Did you know?
WebbSo, based on Hess' law, the enthalpy of solution should be 4.1 k J / m o l. However, the actual enthalpy of solution in this case is 3.88 k J / m o l according to multiple sources. The discrepancy appears to be that the enthalpies of formation for N a X + and C l X − don't exactly equal the combined enthalpy of formation for N a C l ( a q).
