Question

Quizplus · Accepted Answer

Potassium dichromate (K₂Cr₂O₇) is a strong oxidizing agent that can be used in the Breathalyzer test to oxidize the alcohol in a person's breath. When alcohol is oxidized, it produces acetic acid, which can be detected by the Breathalyzer. However, K₂Cr₂O₇ is no longer used in modern versions of the Breathalyzer due to safety concerns regarding its toxicity and carcinogenicity. Therefore, choice C is the only correct answer.
