For saltwater that's as saturated as it can possibly get (i.e. there's no way to dissolve any more salt in it no matter how hard you tried), the freezing point is -21.1 degrees Celsius. This is when the saltwater is 23.3% salt (by weight).-Tamara. p.s. As the water starts to freeze, the salt gets left in the liquid.Web

The easy part is: yes, in still water allowed to reach equilibrium the salt concentration does go up with depth. Saltier water has higher mass density, so the gravitational energy can be lowered that way. The concentration differences go up until the free-energy of creating that big a concentration difference balances the gravitational energy ...Web

Saltwater is a geological term that refers to naturally occurring solutions containing large concentrations of dissolved, inorganic ions. In addition, this term is often used as an adjective in biology, usually to refer to marine organisms, as in saltwater fish. Saltwater most commonly refers to oceanic waters, in which the total concentration ...Web

Salt water density can be determined from known temperature, pressure, and salinity. We all know that temperature can be measured using a thermometer, pressure is measured with a pressure gauge. Measuring the water salinity, which is the total concentration of all dissolved salts in water, is a more complicated problem.Web

Saltwater Fish vs. Freshwater Fish? Fish cells, like all cells, have semi-permeable membranes. Eventually, the concentration of "stuff" on either side of them will even out. A fish that lives in salt water will have somewhat salty water inside itself. Put it in the freshwater, and the freshwater will, through osmosis, enter the fish, causing ...Web
