3. A person was pulled over by a policeman for driving erratically. The policeman gave the driver a breathalyzer test which operates on the principle of the color change from the orange Cr6+ to the green Cr3+ explored in this experiment. A blood sample was also taken from the driver for analysis (the breathalyzer and blood sample were taken at the same time). The breathalyzer test showed a level of 0.10% alcohol (over the legal limit), but the blood test indicated a level of 0.06% alcohol (below the legal limit). Which test do you feel is more representative of the true alcohol content of the person? EXPLAIN. a. Provide a possible reason to explain the discrepancy between the breathalyzer results and the blood analysis results
