Correction to “pH-Dependent Inversion of Hofmeister Trends in the Water Structure of the Electrical Double Layer” Emma L. DeWalt-Kerian, Sun Kim, Md. Shafiul Azam, Hongbo Zeng, Qingxia Liu, and Julianne M. Gibbs* J. Phys. Chem. Lett. 2017, 8 (13) 2855−2861. DOI: 10.1021/acs.jpclett.7b01005 S Supporting Information *



T

he pH 11 spectrum for LiCl was missing, and the pH 10−6 spectra were shown to be 1 pH unit lower than the actual pH based on the color sequence shown in the Figure 1 legend. The properly color-coded LiCl spectra including the pH 11 spectrum are now shown in the revised Figure 1 below. Figure S1 in the Supporting Information has also been corrected to show the raw SFG spectra corresponding to the smoothed data displayed in the revised Figure 1. The revised Figure 1 and Figure S1 do not change the conclusions of the manuscript and are more consistent with the discussed trends.
