Abstract: An electrolysis apparatus for producing chlorine bleach includes an anode plate, a cathode plate spaced apart from the anode plate, one or more inner conductive plates positioned between and spaced apart from the anode plate and the cathode plate, and a sleeve surrounding the anode plate, the cathode plate, and the one or more inner conductive plates. A system for producing chlorine bleach includes, in addition to the electrolysis apparatus, a container having an opening and which is configured to hold a solution of water and salt. The system further includes a power source having a first terminal connected to the anode plate and a second terminal connected to the cathode plate. Upon connecting the anode plate and the cathode plate to the power source and inserting the electrolysis apparatus into the solution, electrolysis of the solution produces chlorine bleach.
