What property quantifies the amount of dissolved salts in water?

Explanation:
Salinity is the property that quantifies the amount of dissolved salts in water. It reflects the concentration of ions like sodium, chloride, and sulfate that are dissolved rather than suspended, typically expressed in practical salinity units or parts per thousand (seawater is about 35 ppt). This matters ecologically because salinity influences osmoregulation, species distributions, and water density, affecting how organisms respond to mixing zones and gradients such as in estuaries. An estuary is a geographic mixing zone, turbidity measures how cloudy the water is due to suspended particles, and temperature describes the water’s heat content, not its salt content.
