Concentrative Properties: Potassium hydrogen phosphate
5.5 to 8
Concentrative properties of aqueous solutions — density, refractive index, molality, molarity, freezing-point depression, and dynamic viscosity as a function of mass percent concentration for 62 solutes. Data from CRC Handbook 97th Edition, Section 5.
