If a solution of a compound has a rotation of +12 degrees, how could you tell if this was actually +12 degrees, or really -348 degrees, or 372 degrees?
Homework Answers
observed rotation = specific rotation * length of the cell and concentration. Since for a given polarimeter, length is fixed and specific rotation is fixed
depending upon the concentration, observed rotation will change.
hence +12 or -348 and 372 degrees depends on concentration.
