Density of hydriodic acid, HI(aq)

Table 1. Estimated values of absolute density (g/cm3) of aqueous hydriodic acid solutions {HI + H2O) as function of electrolyte molality m and temperature T (at pressure p = 1 bar). Values in the table are consistent with the density of pure water calculated with the IAPWS-95 equation of state.

ρ /g·cm−3
m /mol·kg(H2O)−1 T = 10.0 °C T = 25.0 °C T = 40.0 °C T = 55.0 °C T = 70.0 °C T = 85.0 °C
