Strontium carbonate is also used for making some superconductors such as BSCCO and also for electroluminescent materials where it is first calcined into SrO and then mixed with sulfur to make SrS:x where x is typically europium. [citation needed] This is the "blue/green" phosphor which is sensitive to frequency and changes from lime green to blue.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Solubility constants are used to describe saturated solutions of ionic compounds of relatively low solubility (see solubility equilibrium). The solubility constant is a special case of an equilibrium constant. Since it is a product of ion concentrations in equilibrium, it is also known as the solubility product. It describes the balance between ...
In a very large bowl, combine the Chex cereals, Cheerios, pretzels, and mixed nuts. Gently toss the mixture to evenly distribute the ingredients, taking care not to crush the cereal.
The effect of the particle size on solubility constant can be quantified as follows: = + where *K A is the solubility constant for the solute particles with the molar surface area A, *K A→0 is the solubility constant for substance with molar surface area tending to zero (i.e., when the particles are large), γ is the surface tension ...
Every two years, the period between November's election and when the new Congress begins is often the busiest swath of time for the media's coverage of Congress.
