2. Dissolution enthalpies

Table 1 gives the enthalpies of dissolution in water, Δ _dis H, 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 _dis H

Not knowing the uncertainty attached to the values in the original publication, we have kept the same number of significant figures...
