The concentration of salts in seawater
Did you know?
Saline water (more commonly known as salt water) is water that contains a high concentration of dissolved salts (mainly sodium chloride). On the United States Geological Survey (USGS) salinity scale, saline water is saltier than brackish water, but less salty than brine. The salt concentration is usually expressed in parts per thousand (permille, ‰) and parts per million (ppm). The USGS salinity scale defi… WebMost modern sea water desalination plants use reverse osmosis membranes with a recovery of 30–50%, depending on initial concentration of the sea water and other …

WebSharks cope with the salty water by generating lots of the chemical urea. This substance, produced throughout the shark's body, counterbalances the salt in the ocean water. In other words, there's as much salt in the seawater as there is urea (and other chemicals) in the water inside the shark's tissues. So sharks don't lose water the way fish do.
