If pH of salt water should be 7 then why does the normal saline used in iv drips have a pH of 4.5-5.5?

As you state NaCl is the salt of a strong acid and a strong base and should have a neutral pH. However, several sites make the claim that the pH is in the range of 4.5-5.5. It's possible for a neutral solution to have a pH of something other than 7. pH is dependent on temperature, for example, but not that strongly; I can't find the exact ionization constant for water at 37oC, but by interpolation it's going to be somewhere around 13.6. It may be that the NaCl is promoting the dissociation of water to get the ionization constant to around 10; one of the statements in the discussion makes this claim.

Are normal saline solution and sterile water solution the same?
No, saline is water H2O with sodium chloride NaCl, and water is just H2O
Normal Saline what is the classification?
i just want to know the classification of normal saline?It is just a 0.9% solution of table salt (sodium chloride) dissolved in water. By comparison, ocean water is about 3.5% which is much saltier.

Put 0.9g of Nacl in a beaker and add distilled water to make up to 100ml. that is 0.9% Nacl (Normal saline Solution) From Tade Olubunmi Ademola
What is the freezing point of 0.9 percent normal saline?
The melting point of water is lowered by 1.85 degrees Celsius if 29.2 grams of salt are dissolved in each Kg of water (called a "0.5 molal solution" of salt). So normal saline, a 0.9 molal solution), is lowered juts less thantwice this or 3.33 deg C. So normal saline freezes at -3.33 deg C or 26 deg F.

Can you use normal saline in a cpap?
Normal Saline should not be used in the humidifier of your CPAP machine. Only distilled water should be used. The salt in the saline water could build up in the water chamber and introduce bacteria in the air your breathe. If you have further questions regarding this, you should speak with your physician or respiratory therapist.
What is the chemical formula for normal saline?
Saline is nothing more than salt water. Salt is NaCl. Normal saline is a 0.9% solution of NaCl in H2O.
What best describes half-normal saline?
"Normal Saline" is 0.9% salt in water. This is also known as Isotonic Saline, and it contains the same percentage of salt as is normally found in the human body. The taste of tears are a good way of understanding Isotonic or Normal Saline.Half Normal Saline is 0.45% saline in water, and is called Hypotonic Saline. It is dangerous to give this in an IV unless prescribed by a physician after consulting laboratory tests on the patient. This is due to its osmolality.Formal Saline, or Formalin, is 10% salt in water. It is used to preserve lab specimens and in embalming bodies. Formalin is an extremely toxic chemical, and ordinary people should not come into contact with it.
