Following publication of the original article [1], the author has identified three errors.


First, in the first row of Table 1, the values of calcium chloride hexahydrate for 15 °C and for 25 °C had been transposed.


The affected cells are shown below while the full table can be accessed via the online edition of this article.

Second, at the bottom of page 3, in the left-hand column, the equilibrium value for magnesium chloride should be 11 ppb HCl and not 23 ppb.

Last, on page 4, in the upper left-hand column, the pH of a saturated solution is higher than 13, and not equal to ca. 11.3
