For all other acids and at inhibition times below 10 min (or proton concentrations below 60 µmol/g CAC ), no significant differences between the acids can be identified. At higher proton concentrations, i.e., above 60 µmol/g CAC , the trends start to diverge, which means that higher acid concentrations of HClO Regardless of the strong acid type and concentration, only Al(OH) 3 formation is expected prior to the pH swing to alkaline conditions, similar to what is modeled for HCl (Figure ). Calcium salts with perchlorate (Ca(ClO 4 ) 2 -1886 g/L), chloride (CaCl 2 -420 g/L) and nitrate (Ca(NO 3 ) 2 -1520 g/L) are characterized by a high solubility at room temperature, and thus do not form under the experimental conditions studied here. Even the formation of calcium sulfate dihydrate CaSO 4 • 2H 2 O with a solubility of 2.6 g/L should not occur since calcium concentrations do not exceed 0.025 g/L (see SI Table ).
