Question

The correct relation between $S,\theta$ and $C$ for an optically active solution is

• A. $S=\theta LC$
• B. $\theta =SLC$
• C. $L=\theta SC$
• D. $C=\theta LS$

Answer 1

Answer: (B)

For an optically active solution, the angle by which the plane polarized light is rotated is given by:
$\Rightarrow \theta =SLC$
where, $\theta$ is the rotated angle,
$S$ is the correction factor,
$L$ is the path length,
$C$ is the concentration of solution.
