Presentation Transcript
Polarimetry measures the extent to which a substance interacts with plane polarized light (light which consists of waves that vibrate only in one plane); whether it rotates plane polarized light to the left, to the right, or not at all. optically active mean ? [ ]lit= [( )obs]/(lx c)
Purpose: Determine the rate constant (k)of the reaction Total reading will be?
-d[sucrose]/ dt = k [sucrose]m[H2O]n[H+] p -d[sucrose]/ dt = keff [sucrose]m c = co e -keff t
