| Summary: | Alkaline and acid water produced by electrolysis are believed to have health benefits. Alkaline water containing hydrogen for drinking can be an antioxidant that captures free radicals which will increase the immune system, while acidic water serves as an external medicine, antiseptic, or disinfectant. This paper aims to discuss the effect of the potential and the total dissolved solids (TDS) on the electrolysis currents variables. The electrolysis device is made simple utilizing a portable mineral water ionizer of which energy is generated from the solar cells module in Indonesia. The cathode and anode regions were separated by an ion-exchange membrane, the volume of the electrolysis container, the electrode material, and its dimension, were made fixed. The statistical data analysis was performed using linear and multiple regressions showed that the currents electrolysis were strongly influenced by the potential and TDS variables, but the effect of the TDS was more dominant than the potential. The current efficiencies of acidic formation were not significantly affected by electrolysis potentials and TDS, while the current efficiencies of alkaline formation were significantly affected by electrolysis potentials and TDS. © 2021, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.
