Chemistry For Dummies. Nuclear fission occurs when a larger isotope breaks apart into two or more elements. Scientists usually accomplish this task (for some controlled nuclear reactions) by bombarding a large isotope with a second, smaller one — commonly a neutron. The collision results in nuclear fission.Solubility = Constant x Pressure. The "constant" in Henry's law is Henry's constant, and its value depends on the gas, solvent, and temperature. A particularly useful form of Henry's law relates the solubility (S) and pressure (P) between two different states: According to this relationship, tripling the pressure triples the gas solubility.

In this case, the best solution is to drain your hot tub, scrub it, and start over with fresh water.
