Close resemblance of theory (continuous line) with experimental molar concentration of CaCl₂ of the diluate tank (mol·m⁻³) (discrete data points) versus time (min) for specified ED operating conditions: (i) experiment 2 (feed flow rate = 130 mL·min⁻¹; anolyte = 100 mol·m⁻³ HCl; catholyte = 25 mol·m⁻³ Na₂EDTA + 25 mol·m⁻³ AA; applied voltage = 4 V). (ii) Experiment 3 (feed flow rate = 130 mL·min⁻¹; anolyte = 100 mol·m⁻³ HCl; catholyte = 50 mol·m⁻³ Na₂EDTA + 50 mol·m⁻³ AA; applied voltage = 4 V) [13].
