Published on:

Molar conductances at 25°C and depression oj freezing point in the concentration range of 0.01 - 0.20 M aqueous L-ascorbic acid solutions have been measured. The limiting molar conductance and the first dissociation constant oj the acid have been found to be 380.4 S cm2mol -1and 6.03 x 10 smoldm respectively.
