"system to have a negative charge. This breaks the carbon-chloride bond and results in a negatively charged chloride ion. Because the researchers are using electrochemistry, they can meter the rate at which electrons are introduced into the system—which controls how quickly hydrochloric acid is produced... acid used by industries as reagent for chemical reactions... chloride ions used to chlorinate small molecules called arenes which can be used in pharmaceutical and agricultural components
