Does salt water have a higher density than fresh water?

Best Answers

Salt water can be described as heavier than tap water, provided this is understood as “per unit volume” of water. Scientifically stated, a volume of salt water is heavier than an equal volume of tap water because salt water has a higher density than tap water. read more

This makes the density of the salt water higher than that of the fresh water. In general, the density of freshwater is about 1000 kg/m^3 while the density of salt water ranges from 1020 to 1030 kg/m^3, depending upon the concentration of dissolved salts. read more

Saltwater has a higher density than freshwater because of the sodium chloride it contains. Furthermore, cold saltwater is denser than warm saltwater but it becomes less dense when water freezes into ice. The boiling point of seawater is higher than that of pure water, and its freezing point is lower. read more
