    Normal saline has to be in harmony with our bodies which is on the acid end rather than alkaline.

    EDIT NOTES: Ok Mr Chemistry man who gave me a negative - as I so stated Normal Saline (typically given intervenously to ill people) has to be in harmony with the body WHICH IS ON THE ACIDIC END......

    WHAT IS INCORRECT in this?

    "The human body is SLIGHTLY acidic when it is in a state of health. This limits fungal and bacteria growth on the skin or in the body. Some areas of the body are more acidic than this to address local issues and microbial populations. Medical tests for pH level are usually a reference of the BLOOD pH level."

    Body fluids such as blood has a pH that is slightly acidic (probably about 5.7). One would not want to change that because the change could have serious health consequences, so the saline is buffered to a slightly acid pH.

    Evaluating the pH of eight brands of aerosol saline solutions to determine if there is a change in pH during the normal usage of an aerosol canister. The pH measurements were taken over a period of 14 to 24 days with a Corning model 10 pH meter (accuracy +/- 0.05 pH units). The saline was expelled and measured daily in 15-ml increments, the approximate volume used each day by soft lens wearers. We found no significant change in pH within each brand evaluated over the test period. However, there was a statistically significant difference in the median pH of the buffered and the unbuffered aerosol saline solutions. The mean pH of the buffered aerosol saline solutions, which averaged 7.30 pH units, was within the ocular comfort range. The mean pH of the unbuffered aerosol saline solutions, which averaged 5.79 pH units, was outside the ocular comfort range. This indicates that all aerosol saline solutions should be buffered.

    Hope this helps.

    The body's corrective mechanisms--via lungs and kidneys--to correct metabolic acidosis would in most cases be bolstered by an infusion of normal saline, through increased cardiac and renal output. The mild acidity of the solution would in most cases be clinically insignificant. Normal saline bolsters intravascular volume greatly, giving the body a "jump start" to eliminate excess acidity, provided there are no problems such as heart or renal failure which would prevent the body from assimilating a sudden load of extra sodium or water. This volume loading is the main effect of high-sodium infusions, and it probably doesn't make much difference in most cases whether one uses other more ph-balanced solutions such as Ringer's Lactate
