Abstract

The optical rotation and the conductivity of kappa‐carrageenans in aqueous solution have been investigated as functions of temperature in the presence of various electrolytes. The activity coefficients of sodium and potassium have been determined and correlated with the conformation. The potassium activity coefficient under ordered conformation is in agreement with a mechanism of dimerization.
