  2. Aluminium–copper alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–copper_alloys

    Aluminium forms a eutectic with copper at 547 °C and 33 mass percent copper, which also corresponds to the maximum solubility. At lower temperatures, the solubility drops sharply; at room temperature it is only 0.1%. At higher copper contents, Al 2 Cu is formed, an intermetallic phase.

  5. 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.

  6. Aluminium sulfate - Wikipedia

    en.wikipedia.org/wiki/Aluminium_sulfate

    Aluminium sulfate is a salt with the formula Al 2 (SO 4) 3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water [ 3 ] [ 4 ] and wastewater treatment plants , and also in paper manufacturing.

  7. Solubility table - Wikipedia

    en.wikipedia.org/wiki/Solubility_table

    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.
