[vaazu]

Homework Statement

Set up thermodynamic cycle for determining the enthalpy of hydration of Mg2+ ions
The following enthalpies are given
Sublimation of Mg
ionization energies of Mg
dissociation enthalpy of Cl2
electron gain enthalpy of Cl
enthalpy of solution of MgCl2(s)
enhalpy of hydration of Cl-

Homework Equations

The Attempt at a Solution

any hints how to set up the cycle?

 

[Borek]

Is any of the processes mentioned related to Mg²⁺ hydration?

Is any of the processes mentioned related to Mg²⁺ hydration?

yeah, the solvation enthalpy, from solid to liquid, then the enthalpy of Cl- in the solution. The change of the enthalpy in the cycle should be 0, but how to find the difference in the MgCl2(s) and the gas phases?

Sorry, no idea what I was thinking Looks like there is something missing here.
