𝟎 and χ . Another aspect we explore in this study is the dependence of adsorption and desorption reversibility on the cation identity. We perform reverse salt titrations immediately after the forward titration, reducing the salt concentration in a stepwise fashion using the same procedures as the forward titration. The preservation of the timescales from the previous stepwise titration is chosen to determine whether we arrive at the same structural and electrostatic parameters under the same ionic strength conditions and experimental time scale (approximately three hours per forward titration and the equivalent amount of time for the reverse titration).
