Dissolution enthalpies
Water dissolution enthalpies of mineral compounds

Table 1 gives the enthalpies of dissolution in water, Δ_disH, of mineral compounds.

They are expressed in kJ.mol^-1.

The original publication [1] gave heats of dissolution reaction Q expressed in kcal.mol^-1.

Q being the heat released by the dissolution reaction, we have :Q = - Δ_disH

Not knowing the uncertainty attached to the values in the original publication, we have kept the same number of significant figures after converting kcal.mol^-1, into kJ.mol^-1 (1 kcal.mol^-1 = 4.1855 kJ.mol^-1).

Dilutions are always expressed as the number of molecules of solution water per molecule of solute.

In this table, the symbols :
