Abstract The solubility (ms) of sodium bromide (NaBr·2H2O) in water was measured at 283.15—313.15 K and 0.1—300 MPa. The ms decreases with increasing pressure and the coefficient, θ ( = (∂ms/∂p)T/ms), is −10 × 10−5 MPa−1 at 298.15 K and 0.1 MPa. This sign of θ is opposite to that (7 × 10−5 MPa−1) calculated using a thermodynamic equation.
