Freezing point of pure water

WebPure water transitions between the solid and liquid states at 32°F (0°C) at sea level. ... The greater the amount of dissolved salt, the lower the freezing point. Ocean water is about 3.5% salt; sea water freezes at about 28°F (-2°C). A 10% salt solution freezes at about 20°F (-6°C), and a 20% solution freezes at 2°F (-16°C).
