(S)-2-iodooctane is dissolved in acetone, and is found to rotate planepolarized light.One equivalent of radioactive Na131I is added to this solution, and the reaction is monitored by polarimetry. As the reaction proceeds, the specific rotation eventually drops to zero. Further analysis shows that the specific rotation falls to zero after half of the radioactive iodine has been consumed. Explain this observation
Chemists often use molarity ,M in Moles/liter , to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure
