The apparent discrepancy between the experimental data and the model for 1 M, might be related to electrode -specific interactions with the solvent inside the IHP (e.g., higher number of HBs) that are too subtle to be picked up by the contact angle measurements as well as the occurrence of underlying electrochemical reactions that have not been considered in the QM/MD model. The latter have been shown to have a stronger impact on the electrowetting response at lower electrolyte concentrations .
