  7. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    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.

  8. Phosphoric acids and phosphates - Wikipedia

    en.wikipedia.org/.../Phosphoric_acids_and_phosphates

    Phosphoric acid units can be bonded together in rings (cyclic structures). The simplest such compound is trimetaphosphoric acid or cyclo-triphosphoric acid having the formula H 3 P 3 O 9. Its structure is shown in the illustration. Since the ends are condensed, its formula has one less H 2 O (water) than tripolyphosphoric acid.
