The ingested alcohol meets in the
blood and makes the tour of our organs,
without forgetting the brain please.
You wonder
how a ball of breathalyzer can
evaluate the quantity of alcohol content
in blood? The alcohol is routed
by blood until the
pulmonary alveolar and is present therefore in
the air that you exhale. The quantity
of alcohol presents in air is
2000 times weaker than the one
present in blood. While measuring
the quantity of alcohol present in air
expired we can therefore know the quantity of alcohol presents in blood.
The breathalyzer contains an orange product that turns to the blue green in presence of alcohol: the potassium dichromate, an orange color oxidizer, that reacts with the ethylic alcohol to give ions chromium of blue green color and acetic acid.
This reaction is called an oxydo-reduction and the coloration is dependent of the quantity of alcohol.
A quantity defined of orange solution is contained in a ball and the color is mesured after someone blew in. The color is mesured by a photoelectric cell. The introverted data is converted then directly in rate of alcohol level of blood that is displayed on a dial. In the ball, the silver nitrate is added, it is a catalyst.
