I want to resolve to the degree of saturation of a salt solution

AI Thread Summary
To determine the degree of saturation of a salt solution, specific gravity and temperature measurements are essential. While a direct formula for calculating saturation from these values is not readily available, resources like charts and hydrometers can assist in the process. The discussion suggests consulting the book "Densities of aqueous solutions of inorganic substances" for potential formulas related to density and temperature. The user is encouraged to explore chemistry forums for more specialized assistance. Ultimately, finding a precise method for measuring saturation may require experimental data or specialized tools.

I want to measure salt brines. I can measure specific gravity and degrees Fahrenheit. I need a formula that I can insert the two measured values into and get the degree of saturation of my brine. I can't find a formula. I'm not sure a formula exists, but I can't understand why not. There are charts to adjust SG for temperature, and Hydrometers scaled with degree of saturation, called by various names like Brinometer, salometer, salinometer and such, but I don't have one of those. My hydrometer just measures specific gravity and is calibrated at 68 degrees Fahrenheit.

Can you help me? Am I even posting in the right place?

Well, that's certainly NOT a mathematics problem! Not until you have the correct formula. This might help:

Thanks for the reply, and I'll take my question to chemistry and see what happens there.
 
Generally speaking there are no other formulae than best fits to experimental data. Check if you can locate "Densities of aqueous solutions of inorganic substances" by Söhnel and Novotný, published by Elsevier in 1985. Hopefully that's the book I am thinking about, my notes are not clear :frown: and I am not going to drive 15 miles just to check my Uni library (even if I know where the book stands). Honestly, I am sure they have formulae for densities vs temp, not sure if they have formulae for solubility.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
