Question

Part A. Besides vodka, there are other colorless alcohol-containing beverages that can be titrated following the procedure in your lab. Given the average values for the percent alcohol by volume listed in the table below, which beverage do you expect to use the least amount of iron (II) standard solution during the titration? Assume all lab procedures stay the same.

Part B. The Grey Moose vodka tested in this lab reports a percent alcohol by volume of 40.0% on its label. How does your value compare to the reported one? If the values are different, give one possible experimental error that might have contributed to the difference.-For this one I received 37.5, I'm just not sure of the experimental error that could have occured.

Really need assitance with these lab problems! Thank you :)

Explanation / Answer

Part A
White whine has lowest % alcohol by volume (12%).
It will use the least amount of iron (II) standard solution during the titration.
Part B
One experimental error could be that iron (II) standard solution is not properly standardized. The actual concentration of iron (II) standard solution might be different than the one you use in your calculations. Other error might be that the glassware used for the titration is not caliberated.
