Clayton, the chemistry of aqueous solutions of various salts has been a laboratory standard for a very long time. The reason for variability is results is in the test method not the chemistry.

I believe the scientific validity, but I fear there are too many variables in the common setting. Like others have stated, specific amounts of water to salt would be very helpful. And do different forms of salt make a difference?
