Correction: Saturated salt solutions in showcases: humidity control and pollutant absorption

Correction: Heritage Science (2022) 10:54 https://doi.org/10.1186/s40494-022-00689-3

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.

Correct version

Table 1 DRH of relevant salts at various temperatures

Chemical name	Formula	15 °C	20 °C	25 °C
Calcium chloride hexahydrate	CaCl2‧6H2O	34.1%	30.9%	28.1%

Incorrect version

Table 1 DRH of relevant salts at various temperatures

Chemical name	Formula	15 °C	20 °C	25 °C
Calcium chloride hexahydrate	CaCl2‧6H2O	28.1%	30.9%	34.1%

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

The original article [1] has been corrected.
