Breathalyzer reaction
Web8 rows · Mar 1, 2024 · Principle: The breathalyzer is a redox reaction. When the potassium dichormate reacts with ethanol it loses an oxygen atom (gets reduced), going from the orange dichromate to the green chromium sulfate. At the same time dichromate is being … WebA fuel cell measures alcohol content by creating a chemical reaction that oxidizes the alcohol in the breath sample and produces an electrical current. The more alcohol that is oxidized, the greater the current. The current is measured to determine the subject's BAC. Fuel cell breathalyzers are used by individuals desiring the highest level of ...

It is measured with a spectrophotometer. The more it decreases, the higher the blood alcohol content. Legal … 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.
WebJun 22, 2012 · Based on the proton-electron exchange in a breathalyzer, more alcohol molecules will result in a greater number of electrons generated from a catalytic chemical reaction. The electrons generated then drive the electrical current that is measured by a microprocessor to indicate the amount of alcohol content proportional to BAC.
