Would you expect the conductivity of saturated solutions of barium chloride and barium sulphate in water to differ? Explain your answer.
Answers
Answer:
Barium Sulfate is the sulfate salt of barium, an alkaline, divalent metal. Barium sulfate is quite insoluble in water, and is used as a radiopaque agent to diagnose gastrointestinal medical conditions. Barium sulfate is taken by mouth or given rectally. (NCI04)
NCI Thesaurus (NCIt)
Barium sulfate appears as white or yellowish odorless powder or small crystals. Mp: 1580°C (with decomposition). Density: 4.25 -4.5 g cm-3. Insoluble in water, dilute acids, alcohol. Soluble in hot concentrated sulfuric acid. Used as a weighting mud in oil-drilling, in paints, paper coatings, linoleum, textiles, rubber. Administered internally ("barium cocktail") as a radio-opaque diagnostic aid.
CAMEO Chemicals
Barium sulfate is a metal sulfate with formula BaO4S. Virtually insoluble in water at room temperature, it is mostly used as a component in oil well drilling fluid it occurs naturally as the mineral barite. It has a role as a radioopaque medium. It is a barium salt and a metal sulfate.

Answer:
- Yes, I would expect the conductivity of saturated solutions of Barium Chloride and Barium Sulphate in water to differ, since Barium Chloride is soluble in water which means that as it dissolves, the ions are freely movable in motion as compared to Barium Sulphate which is insoluble in water, a small amount of barium ions and sulphate ions break away from the surface of the solid and the state remains solid.
- Solids conduct heat better than liquids, as the particles in a solid are most tightly bond and their positions are more fixed relative to each other, thus liquids are usually poor conductors of heat due to their free motion of particles.
- Therefore, as the amount of ions in solution increases, so does the conductivity of the solution, which justifies that, Barium Chloride conductivity is more than that of Barium Sulphate.
