pH is an important variable in a process that involves the mixing of the acid base, with nonlinear properties of linear controllers often leads to reduced performance. Syahrizal Ismail (2010) has been conducting design build controller pH (HCl and NaOH titration) using the auto switch PID, and...
With the identical measurement condition, the obtained Cl2 gas volume is lower than that of H2 gas because some Cl2 that was generated at the anode undergoes hydrolysis (Cl2 + H2O → HClO + HCl). The HClO and Cl2 in the electrolyte were determined using the iodometric titration...
