The Complete Aqueous Phosphoric Acid Solutions Density-Concentration Calculator

This calculator calculates for concentration or density values that are between those given in the table below by a process called interpolation. Input a temperature and density within the range of the table to calculate for concentration or input concentration to calculate for density. The table below gives the density (kg/L) and the corresponding concentration (% weight) of Phosphoric acid (H3PO4) solutions in water at different temperatures in degrees centigrade (°C). The table was taken from "Perry's Chemical Engineers' Handbook" by Robert H. Perry, Don Green, Seventh Edition. Please see the Examples page for more details.
