Abstract: Disclosed herein are processes comprising electrolyzing an aqueous solution comprising lithium, wherein the aqueous solution has a pH less than 0.5. Also disclosed are processes comprising electrolyzing a first aqueous solution comprising lithium to obtain a second aqueous solution comprising lithium, and an acidic aqueous solution having a pH less than 0.5, adjusting the pH of the second aqueous solution with the acidic aqueous solution to obtain a third aqueous solution comprising lithium having a pH less than 0.5, and electrolyzing the third aqueous solution comprising lithium. Additionally disclosed are, processes comprising stripping a liquid medium comprising lithium with an acidic aqueous solution to obtain an aqueous solution comprising lithium, and electrolyzing the aqueous solution comprising lithium. Further disclosed are processes for preparing a liquid medium comprising lithium.
