Chemistry: How a breathalyzer test works
By: Lime Red Tetrahedron
When a breathalyzer test is administered, the subject breaths into the device, where any ethanol in the breath becomes involved in a redox reaction with acidified potassium dichromate(VI) K2Cr2O7. Any alcohol is oxidized into ethanoic acid. Orange Cr(VI) is reduced to green Cr(III).Cr2O7-2 +...
