  2. Barium chloride - Wikipedia

    en.wikipedia.org/wiki/Barium_chloride

    Barium chloride is extracted out from the mixture with water. From water solutions of barium chloride, its dihydrate (BaCl 2 ·2H 2 O) can be crystallized as colorless crystals. [2] Barium chloride can in principle be prepared by the reaction between barium hydroxide or barium carbonate with hydrogen chloride. These basic salts react with ...

  3. Spectator ion - Wikipedia

    en.wikipedia.org/wiki/Spectator_ion

    A spectator ion is an ion that exists both as a reactant and a product in a chemical equation of an aqueous solution. [1] For example, in the reaction of aqueous solutions of sodium carbonate and copper(II) sulfate: 2 Na + + CO 2− 3 (aq) + Cu 2+ (aq) + SO 2− 4 (aq) → 2 Na + (aq) + SO 2− 4 (aq) + CuCO 3

  4. Sodium bisulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_bisulfate

    Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4. Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).

  5. Barium perchlorate - Wikipedia

    en.wikipedia.org/wiki/Barium_perchlorate

    The need for dehydrating compounds has increased with the use of chemical reactions employing gases under pressure, as the water must be removed from the air prior to the reaction taking place. [8] Barium perchlorate is also used for the determination of small concentrations (down to 10 ppm, with an accuracy of +/- 1 ppm) of sulfate. [5]

  6. 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.

  7. Sodium sulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_sulfate

    Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.

  8. Barium chlorate - Wikipedia

    en.wikipedia.org/wiki/Barium_chlorate

    Barium chlorate can be produced through a double replacement reaction between solutions of barium chloride and sodium chlorate: . BaCl 2 + 2 NaClO 3 → Ba(ClO 3) 2 + 2 NaCl. After concentrating and cooling the resulting mixture, barium chlorate precipitates.

  9. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl ...
