One major way to tell is whether they would live in a lake (freshwater) or in the ocean (saltwater).

∙ 13y agoA person can float in saltwater because it is denser than freshwater. The salt in the water increases its density, making it easier for objects like the body to float. This difference in density is why a person can float in saltwater but not in freshwater.
Springs are simply freshwater. But some of the fish, if any, in springs are salt and fresh water fish. Think of ponds and rivers and lakes. Those are all freshwater too. One more fact that I have to tell you is that water should be stored in a cool, dark, and dry place.
the amount of salt dissolved in the water
The biggest fresh water fish is the great sturgeon reaching 23 feet in total
The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
All I can tell you is water, rocks, and dirt. Sorry if that is not enough
Salt is the solute. Water is the solvent. Salt water is the solution. This solution is sometimes called a saline solution.
You can evaporate it.

One way to determine if you have a saltwater turtle or a freshwater turtle is by looking at their habitat preferences. Saltwater turtles, like sea turtles, primarily live in the ocean, while freshwater turtles inhabit bodies of freshwater like ponds, lakes, and rivers. Additionally, you can also consider the physical characteristics of the turtle species, as saltwater turtles may have adaptations for living in the ocean, such as flippers for swimming.
You can tell when you reach the solubility of salt in water when no more salt dissolves in the water and there are visible salt crystals at the bottom of the container. This indicates that the solution is saturated, meaning it has reached its maximum capacity to dissolve salt at that temperature.
By the salinity or salt level in the water which can be measure by a number of devices most commonly the hydrometer or refractometer.
