Breathalyzer reaction
WebBreathalyzer definition, a brand of breath analyzer. See more. Web1. Spectrophotometric Analysis: The chemistry of the Breathalyzer® reaction. This experiment determines the ethanol content of an unknown liquid sample using the redox reaction between ethanol and potassium dichromate. A series of ethanol standard solutions are prepared and used to create a standard absorbance curve using a spectrophotometer.

Webbreathalyzer, breathalyser noun. a device that measures chemicals (especially the alcohol content) in a person's expired breath. Synonyms: breathalyser. WebThe Breathalyzer is the oldest breath alcohol analyzer; it is based on the principle of color change of potassium dichromate solution in the presence of alcohol and then analysis using spectroscopy after a specified time to ensure complete reaction. The analyzer contains two vials of chemical cocktail.
