Respuesta :
The combined heat of hydration for the ions in sodium acetate (NaC₂H₃O₂) is : -745kJ/mol
The heat of hydration is described as the quantity of energy produced when one mole of ions undergo a hydration process.
It is a specific form of dissolution energy and the solvent used is water.
ΔH lattice =763 kJ/mol
ΔH soln = 17.3 kJ/mol
The heat (enthalpy) of solution is sum of lattice and hydration energies,
that is, ΔH soln = ΔH hydration + ΔH lattice
ΔH hydration= ΔH solution- ΔH lattice
= 17.3kJ/mol - 763kJ/mol
ΔH hydration= -745kJ/mol
the combined heat of hydration for the ions in sodium acetate (NaC₂H₃O₂ is : -745kJ/mol
