Breathalyzers determine the alcohol content in a person’s breath by a redox reaction using dichromate ions (the unbalanced reaction is shown below).
C2H5OH + Cr2O72− → CH3CO2H + Cr3+
a. Determine the number of electrons transferred in this redox reaction.b. Determine the concentration (in M) of Cr3+ in 50.0mL of solution at the Canadian legal blood alcohol concentration limit (BAC, limit is 0.08 mg/mL).
