what are the properties of saltwater. what are the properties of drinking water.?

Question

i am doing a school project and i am trying to get help with some of the properties of saltwater and drinking water and how long the water can last in heat,

Answer 1

Salt water (that is, sea water) contains many different chemicals in solution. The most abundant, of course, is NaCl, or sodium chloride. It (and the others) are transported by rivers to the ocean as very dilute solutions, which build up over time. Sea water contains about 35 parts NaCl per thousand parts water (probably not coincidentally the salinity of tears in humans). The salts and other dissolved substances lower the freezing temperature of the water, and so seawater is very difficult to freeze. The dissolved substances also change the index of refraction (because the density of the seawater is higher), and raises the boiling point. Sea water has a slightly higher viscosity than fresh water, as well.

Drinking water (by this I am referring to pure H2O, not out of the tap) has well established properties, such as boiling point of 100 degrees celsius and freezing point of 0 degrees celsius. Both sea water and fresh water, when cooled, reach a maximum density (sea water at about 4 degrees), below which density decreases, and reaches a minimum when the freezing point is reached. It is for this reason that ice floats on water, and also, if ice were denser than water, the worlds ice would sink to the ocean bottom, and very quickly the oceans would freeze.

Finally, both sea- and fresh water are "universal solvents", so called because they dissolve such a wide variety of substances. This is one result of their molecular structure (the water part, that is), being a "polar" molecule, with a distinct difference in electrical charge at either end of the V-shaped molecule ( the points of the "V" hold the hydrogen and the acute angle of the "V" is the oxygen.

This is rather lengthy, but I hope it helps.

Answer 2

Saltwater comes from the seas and can last for almost ever. Drinking water is usually from reseviors and springs and it depends on the weather as to how long they last . If there should be a drought the water reseviors and springs could driy up. You need rain to keep these flowing. Hope this answers your questions.

Answer 3

the properties of saltwater is a chemical property and drinking water is physical property.
