Understanding Barium Sulfate's Water Resistance

Barium sulfate (BaSO₄) exhibits exceptionally low water solubility at 0.0024 g/L at 20°C, a property rooted in its crystalline structure and high lattice energy. This insoluble characteristic makes it valuable for:

Radiographic contrast media
High-temperature lubricants
Corrosion-resistant coatings

Comparative studies show BaSO₄ dissolves 10,000 times slower than calcium sulfate in aqueous environments, based on OECD 105 test data.

Solubility Comparison Across Sulfate Compounds

The table below demonstrates barium sulfate's unique position among sulfate compounds:

Compound	Solubility (g/100mL)	K_sp

FAQS on is barium sulfate soluble in water

Q: Is barium sulfate soluble in water?

A: No, barium sulfate is practically insoluble in water. Its solubility is extremely low, approximately 0.00245 g/L at 20°C. This property makes it useful in medical imaging and industrial applications.

Q: Can barium sulfate dissolve in water under normal conditions?

A: No, barium sulfate does not dissolve in water under standard conditions. Its strong ionic lattice structure resists dissociation in water. Even at high temperatures, solubility remains negligible.

Q: Why is barium sulfate considered insoluble in water?

A: Barium sulfate has a high lattice energy due to its sulfate ion (SO₄²⁻) and barium ion (Ba²⁺) bonding. This energy outweighs the hydration energy, preventing dissolution. Its solubility is chemically classified as "sparingly soluble."

Q: How does barium sulfate's solubility compare to other barium compounds?

A: Unlike barium sulfate, many barium compounds (e.g., barium chloride) are highly water-soluble. Barium sulfate’s insolubility is unique, attributed to its stable ionic structure, reducing toxicity risks in specific applications.

Q: Is barium sulphate soluble in polar solvents like water?

A: No, barium sulphate (BaSO₄) is not soluble in polar solvents such as water. Despite water’s polarity, the compound’s strong ionic bonds prevent significant dissolution, even in highly polar environments.
