breath analyser
How does a breath analyzer work?
good! good! good! Here is a curious fellow who has put up a question that trully worth of questions, and before the arrival of a "Do ur own homework" I think I had the answer. Listen friend, Imagine, you're drunk and caught and told to undergo breath analyzer test. You will be told in Brath. like you're drunk and since alcohol (ethyl alcohol of course) is volatile, with alcohol vapor you exhale through the device goes, there is a conatainer it which contain orange colored Acidified (H2SO4) Potassium di chromate (K2Cr2O7) solution, which when in contact with alcohol vapor is reduced in green colored Chromic sulfate [Cr2 (SO4) 3] Ethanol itself is oxidized to colorless acid, not harmful to the change in color. The change in color from orange to green means you are drunk, the intensity the green color is of course dependent on the amount of the Chromic sulfate formed, depending on the amount of potassium di chromate responded that in turn give the amount of alcohol vapor present in your breath that is the extent to which you are drunk. there is a suitable proxy for the intensity of the color green to measure, and thus to measure the level of alcohol present in your body.
