Abstract
The enthalpies of dilution of boric acid in the molality range 0.7 to 0.1 mol kg-1 have been measured at 283.15, 288.15, 298.15, 303.15, and 323.15 K. The enthalpy of dilution to infinite dilution, ΔH∞ ail, of boric acid was found to vary linearly with molality m according to the relation(Δ Hd i l ∞ / c a lt h m o l- 1 = - {- 137.79 + 6.79 (T / K - 273.15) - 0.19 (T / K - 273.15)2; + 0.002 (T / K - 273.15)3} m / m o l k g- 1,)where T is the temperature. The average deviation was ± 0.15 calthmol-1 over the entire temperature range studied.
