Volumetric and Isopiestic Studies of (H2O+k2Hpo4+kh2Po4) at 25-Degrees-C
Density and water activity in (H2O + K2HPO4 + KH2PO4) have been measured at 25 degrees C. The densities were measured by oscillating tube densimeter, and the water activities were obtained by an improved isopiestic technique. The results were correlated with semiempirical equations.
