An optical rotation study gives a result of +140 degrees. Suggest a dilution experiment to test whether the result is indeed +140 degrees, not -220 degrees.

Dilute by a factor of 10. Rotation will be +14 if it is 140 or -22 if it is -220. The direction you turn the polarimeter control will tell you which. Check my thinking.
