A) +2.6°
B) −2.6°
C) 0°
D) +5.2°
E) −5.2°

E) −5.2°

Quizplus · Accepted Answer

The specific rotation of a substance does not change upon dilution or mixing with another substance, so the specific rotation of the resulting solution will be the same as substance one, which is +2.6°. Thus, the answer is choice C, 0°.
