They are highly similar in chemical composition, as carbamide peroxide breaks down into hydrogen peroxide when applied to the teeth. During a teeth whitening procedure, it is the hydrogen peroxide that becomes oxidized and breaks the double chemical bonds of the chromogens, scattering their molecules. Because stains result from accumulations of chromogens, once scattered they appear lighter in color.<\/span><\/p>\n<ul style=\"list-style-type: square;\">\n<li aria-level=\"1\">\n<h3><span class=\"ez-toc-section\" id=\"_Applications_of_Redox_Reaction_in_Electrochemistry\"><\/span><span style=\"font-family: tahoma, arial, helvetica, sans-serif; font-size: 12pt;\"><b>\u00a0Applications of Redox Reaction in Electrochemistry<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\"><span style=\"font-weight: 400;\">The battery used for generating <a style=\"text-decoration: underline;\" href=\"https:\/\/www.electrical4u.com\/dc-current\/\" target=\"_blank\" rel=\"noopener\">DC current<\/a> uses redox reaction to produce electrical energy.<\/span> <span style=\"font-weight: 400;\">Batteries or electrochemical cells used in our day-to-day life are also based on redox reactions.
