Maximum solubility of NaCl in water at 25°C is 357 mg/ml (26.3%). NaCl is unusual in that its solubility does not increase appreciably with temperature, since at 100°C, the solubility is 384 mg/ml. The density of a saturated solution at 25°C is 1.202 g/ml. A saturated solution (23% w/v) freezes at -20.5°C (5°F).
