3. You’ve gotten your hands on a sample of carvone, but you
aren’t sure which enantiomer you have, or how enantiopure it is.
You find that it has a specific rotation of [α]D25 = –52.5°. The
specific rotation of enantiopure (S)-carvone is +61°. Show all
work.
(a) Which enantiomer does your sample contain?
(b) What is the enantiomeric excess of your sample? Show your
work.
(c) What percent composition of each enantiomer present in your
sample?

The percentage of arsenic in a sample can be determined by
titration with iodine. In the determination, all of the arsenic
(As) in the sample is converted to HAsO2 followed by titration with
iodine (I2) solution. The chemical equation for the reaction
between HAsO2 and I2 is:
HAsO2 (aq) + I2 (aq) + 2 H2O (l) → H3AsO4 (aq) + 2 H+ (aq) + 2 I
− (aq)
In an actual analysis, a 0.7034 g sample is dissolved and the...
