'esides, "inegar will be added into the saltwater solution to increase power Stoppin# me%hanism( %he stopping mechanism is based on redo/ reaction, especially #odometri with 4ydrogen .ero/yde as the o/ydator of iodide ion and ascorbic acid as the reductor of #odine solution! %riiodide %riiodide ion that is formed from the reaction between iodide ion and iodine can make a comple/ form with amylum which cause the solution turn into dark blue! %he time needed "ary with the concentration of iodine added! 5hen the solution turn into dark blue (the light cannot go through the solution and reach the photoreceptor sensor), the motor circuit will be automatically open and thereby stop the car! car!
