This is to do with the process of osmosis. Osmosis is the movement of water from a region of high concentration to an area of low water concentration. If someone is dehydrated, their cells won't have much water in their cytoplasm, so giving them pure water would cause their cells to take up so much water that they would rupture. Small amounts of salt are added to reduce this damaging effect. ---------------------- read about hypernatremia.

Why is it preferable to use a saline solution rather than mercury in manometer?

Using a saline solution is preferable to mercury in a manometer because saline is non-toxic and safer to handle. In case of accidental spillage, saline is less harmful to humans and the environment. Additionally, saline is more commonly available and easier to dispose of compared to mercury.


Would ice bergs melt faster if the oceans were pure water?

Yes, because saline water has low freezing point as compare to distilled water or pure water.


What is the frozen expansion volume of saline water?

The frozen expansion volume of saline water varies according to the solution, freezing temperature, as the air bubbles are not uniform. The density of frozen saline water is approximately 0.9 gm/L compared to pure ice which is 0.9 gm/L. It has an overall comparison ratio of approximately 0:8.


Are normal saline solution and sterile water solution the same?

No, normal saline solution contains salt (sodium chloride) dissolved in water, while sterile water solution is pure water without any added salts or other substances. Normal saline is commonly used for medical purposes such as IV fluids or wound cleansing, while sterile water may be used for specific procedures where electrolytes are not needed.


In hospitals when patients get IV's why is the solution not pure water?

If the solution were pure water you would die. When blood cells are exposed to pure water the increased salts in the cell cause the water to flow in and would cause the red blood cells to burst (this is called lysis). The blood itself is a little salty (which is why you rinse your eyes with saline). The IV bags are usually plain saline, sometimes they are saline mixed with a form of sugar. The sugar provides energy for the body. (it is not table sugar)

Is saline solution a pure substnace?

A saline solution is a homogeneous mixture because its appearance and composition are uniform throughout the solution. A substance is salt. A saline solution is a combination of the two substances water and salt. However, in the salt-water solution, the salt is completely dissolved in the water.


Which is more viscous pure water or saline water?

Saline water is more viscous than pure water because the presence of dissolved salts increases the resistance to flow, making it thicker. This higher viscosity can be attributed to the interaction between the salt ions and water molecules, creating more friction as the liquid moves.


What ingredients does salt water have?

Pure saline water is only a solution of sodium chloride in water.

Is frozen salt water heavier than frozen water?

The density of saline water is greater than the density of pure water.


Does saline freeze?

Yes, saline can freeze. Saline is a solution of salt dissolved in water, and the freezing point of saline is lower than that of pure water. Therefore, saline can freeze at temperatures below 0 degrees Celsius.


How will you prepare crystals of pure common salt from sea water?

We can use evaporation method. water will evaporate from saline water on heating and salt is left behind.


Under what conditions mixed bundling preferable to pure bundling?

Mixed bundling is preferable to pure bundling when: - Demands are somewhat negatively correlated. - Marginal production costs are significant.

How can boiling point be used to find out if a substance is pure?

At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.
