Sodium Sulfite
Sodium sulfite is used as a chemical addition to swimming pools to rapidly reduce the chlorine level.
-
Oxidation
Oxidation is the chemical process that occurs when oxygen is exposed to another substance, combining with the substance by sharing its electrons.
-
Sequestering Agent
Sequestering agents are chemicals added to swimming pools to bind with metals found in pools, keeping more metal in the water.
-
Plating
Plating is a chemical process where a metal particles are deposited onto the surface of an electrically charged substance, and can occur in swimming pool water that has exceedingly high concentrations of metal.
-
Fading Endpoint
Fading endpoint is a situation occurring during testing of calcium hardness where the tested water sample turns purple instead of the expected blue color.
-
Ionization Energy
Ionization energy generally describes the energy required for an atom to give up an electron. The higher the ionization energy, the less likely the atom will give up an electron.
-
Magnesium
Magnesium is a mineral found naturally in swimming pool water, as local water sources usually contain magnesium.
-
Soft Water
Soft water describes water that has a greatly reduced amount of dissolved minerals in the water, creating a corrosive environment in swimming pools.
-
Hard Water
Hard water describes the extent to which various minerals are dissolved in water.
