Interpretation Introduction

Interpretation: The specific rotation of a mixture of 68% (+)-tartaric acid and 32% ()-tartaric acid is to be calculated on the basis of given information.

Concept introduction: The concentration of the compound affects the rotation of polarized light in Polarimeter. The rotation is also dependent upon the length of the cell and optical activity of the compound. Optical purity of a compound is measured by the enantiomeric excess.

To determine: The specific rotation of a mixture of 68% (+)-tartaric acid and 32% ()-tartaric acid.
