  2. Barium sulfate - Wikipedia

    en.wikipedia.org/wiki/Barium_sulfate

    Barium sulfate produced in this way is often called blanc fixe, which is French for "permanent white". Blanc fixe is the form of barium encountered in consumer products, such as paints. [5] In the laboratory barium sulfate is generated by combining solutions of barium ions and sulfate salts.

  3. 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.

  5. Barium chloride - Wikipedia

    en.wikipedia.org/wiki/Barium_chloride

    In aqueous solution BaCl 2 behaves as a simple salt; in water it is a 1:2 electrolyte [clarification needed] and the solution exhibits a neutral pH. Its solutions react with sulfate ion to produce a thick white solid precipitate of barium sulfate. BaCl 2 + Na 2 SO 4 → 2 NaCl + BaSO 4

  6. Barium - Wikipedia

    en.wikipedia.org/wiki/Barium

    Unlike calcium hydroxide, it absorbs very little CO 2 in aqueous solutions and is therefore insensitive to atmospheric fluctuations. This property is used in calibrating pH equipment. Barium compounds burn with a green to pale green flame, which is an efficient test to detect a barium compound.

  7. Barium sulfate suspension - Wikipedia

    en.wikipedia.org/wiki/Barium_sulfate_suspension

    The use of barium during pregnancy is safe for the baby; however, X-rays may result in harm. [4] Barium sulfate suspension is typically made by mixing barium sulfate powder with water. [1] It is a non-iodinated contrast media. [5] Barium sulfate has been known since the Middle Ages. [6] In the United States it had come into common medical use ...

  8. Sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfate

    Radium sulfate is the most insoluble sulfate known. The barium derivative is useful in the gravimetric analysis of sulfate: if one adds a solution of most barium salts, for instance barium chloride, to a solution containing sulfate ions, barium sulfate will precipitate out of solution as a whitish powder. This is a common laboratory test to ...

  9. Barium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Barium_hydroxide

    Its aqueous solution, being highly alkaline, undergoes neutralization reactions with acids. It is especially useful on reactions that require the titrations of weak organic acids. Thus, it forms barium sulfate and barium phosphate with sulfuric and phosphoric acids, respectively.
