dialysis
the density of surface seawater ranges from about 1020 to 1029 kg/m, depending on the temperature and salinity. at a temperature of 25 °c, salinity of 35 g/kg and 1 atm pressure, the density of seawater is 1023.6  kg/m. deep in the ocean, under high pressure, seawater can reach a density of 1050 kg/m or higher. the density of seawater also changes with salinity. brines generated by seawater desalination plants can have salinities up to 120 g/kg. the density of typical seawater brine of 120 g/kg salinity at 25 °c and atmospheric pressure is 1088 kg/m. seawater ph is limited to the range 7.5 to 8.4. the speed of sound in seawater is about 1,500 m/s (whereas speed of sound is usually around 330 m/s in air at roughly 1000hpa pressure, 1 atmosphere), and varies with water temperature, salinity, and pressure. the thermal conductivity of seawater is 0.6 w/mk at 25 °c and a salinity of 35 g/kg.

seawater, or salt water, is water from a sea or ocean. on average, seawater in the world's oceans has a salinity of about 3.5% (35 g/l, 599 mm). this means that every kilogram (roughly one litre by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). average density at the surface is 1.025 kg/l. seawater is denser than both fresh water and pure water (density 1.0 kg/l at ) because the dissolved salts increase the mass by a larger proportion than the volume. the freezing point of seawater decreases as salt concentration increases. at typical salinity, it freezes at about . the coldest seawater ever recorded (in a liquid state) was in 2010, in a stream under an antarctic glacier, and measured . seawater ph is typically limited to a range between 7.5 and 8.4. however, there is no universally accepted reference ph-scale for seawater and the difference between measurements based on different reference scales may be up to 0.14 units.
