Buffer capacity \( {\beta}_{\mathrm{H}}^S \) vs pH for the “Gibbsite—saturated aqueous solution” system. Concentrations (mol/L): \( {\mathrm{C}}_{\mathrm{F}}^0:1=5\cdot {10}^{-7},2=5\cdot {10}^{-6},3=5\cdot {10}^{-5},4=5\cdot {10}^{-4},{\mathrm{C}}_{\mathrm{A}1}^0={\mathrm{C}}_{\mathrm{O}\mathrm{rg}}^0={\mathrm{C}}_{\mathrm{P}{\mathrm{O}}_4}^0={\mathrm{C}}_{\mathrm{S}{\mathrm{O}}_4}^0=1\cdot {10}^{-4},{\mathrm{C}}_{\mathrm{C}{\mathrm{O}}_3}^0=1\cdot {10}^{-3} \)
