This dataset comprises the measurements of interaction free energy versus surface separation presented in manuscript entitled "Speciation and hydration forces in sodium carbonate/bicarbonate aqueous solutions nanoconfined between mica sheets". Data for interaction free energy and surface separation are presented for each solution composition, as described in the manuscript and supplemental material.
Each folder contains the data for a specific solution composition. All folders contain data obtained from approach of the surfaces, and where necessary, data from one or more surface retractions.
Each .csv file displays the surface separation in nm (column A) and the interaction free energy in mJ m^-2 (column B).
