Salt peter, Sal Ammoniac, and Sodium Sulfate powders mixed into water.
I have a century old notebook that indicates about 4 oz. (1.3 oz. of each of the above 3 chemicals (powdered THEN mixed)) per gallon of water will absorb enough heat to reduce the temperature to as little as -20 degrees F for as much as 15 minutes or more.
I would appreciate it if someone could provide the results of the reaction, including the heat absorbed (preferably in BTUs, but I can convert CGS units).
Additionally, is it possible to guesstimate the approximate time for the solution to achieve equilibrium?
Presumed left side of the reaction equation:
KNO3 + 2NH4Cl + Na2SO4 + H2O =
What is the corrected complete equation?

Re: Making it COLD!
No chemical reaction happens in this case. Salts are ionized by the water and that takes the heat from the solution:Uriahdribble wrote:Salt peter, Sal Ammoniac, and Sodium Sulfate powders mixed into water.

KNO3(s) = KNO3(aq)
NH4Cl(s) = NH4Cl(aq)
Na2SO4(s) = Na2SO4(aq)
or the a same but in the net ionic form:
KNO3(s) = K+(aq) + NO3-(aq)
NH4Cl(s) = NH4+(aq) + Cl-(aq)
Na2SO4(s) = 2Na+(aq) + SO42-(aq)

I just started a new job, and am full of new germs, and being stressed, so I developed a really bad head cold. My throat is completely fine, and my lungs are fine, I just have a stuffed runny nose and this is making my mouth dry, and my nose sore.
It feels like a constant headache because my nose is so stuffed, and I'm on my period as well, so I've been taking Cold FX, and Midol daily, but nothing is really helping, I'm still achy and cold all over, how would you go about relieving the pain/fixing the cold?
